Answer:
5. 0.5 m/s
6. 2.06 m/s
7. 0.22 m
Explanation:
From the question given above, the following data were obtained:
Horizontal range (Rₓ) = 0.21 m
Time of flight (T) = 0.421 s
Time (t) to reach the top = 0.2105 s
5. Determination of the horizontal velocity of the ball.
Horizontal range (Rₓ) = 0.21 m
Time of flight (T) = 0.421 s
Horizontal velocity (vₓ) =?
Rₓ = vₓ × T
0.21 = vₓ × 0.421
Divide both side by 0.421
vₓ = 0.21 / 0.421
vₓ = 0.5 m/s
Thus, the horizontal velocity is 0.5 m/s.
6. Determination of the initial vertical velocity of the ball.
Time (t) to reach the top = 0.2105 s
Final vertical velocity (vբᵧ) = 0 m/s
Acceleration due to gravity (g) = 9.8 m/s²
Initial vertical velocity (vᵢᵧ) =?
vբᵧ = vᵢᵧ – gt (ball is going against gravity
0 = vᵢᵧ – (9.8 × 0.2105)
0 = vᵢᵧ – 2.06
Collect like terms
0 + 2.06 = vᵢᵧ
vᵢᵧ = 2.06 m/s
Thus, the initial vertical velocity of the ball is 2.06 m/s.
7. Determination of the maximum height reached by the ball.
Time (t) to reach the top = 0.2105 s
Acceleration due to gravity (g) = 9.8 m/s²
Maximum height (h) =?
h = ½gt²
h = ½ × 9.8 × 0.2105²
h = 4.9 × 0.2105²
h = 0.22 m
Thus, the maximum height reached by the ball is 0.22 m

If a small planet were located 8.0 times as far from the sun as the Earth is, how many years would the planet take to orbit the sun?
Answers
Answer:
the time period is 22.63 years
Explanation:
The computation of the number of years taken is as follows:
According to the Keplers law
[tex]T^2 \propto R^3[/tex]
Here T denotes the time period
And, R denotes the average distance among the sun and planet
Now let us assume for earth
R_1 & T_1 be 1 year
So, for Planet
[tex]R_2 = 8R_1 , T_2 = ?[/tex]
Now applied Keplers law
[tex](\frac{T_2}{T_1})^2 \propto (\frac{R_2}{R_1})^3\\\\(T_2)^2 = (\frac{8R_1}{R_1})^3 \times 1^2\\\\(T_2)^2 = 512\\\\T_2 = 22.674[/tex]
So, the time period is 22.63 years

A projectile is launched with an initial velocity 60m/s at an angle 60° to the vertical. What the magnitude of it's displacement after 5s.
Answers
Answer:
the magnitude of the displacement after 5s is 137.31 m.
Explanation:
Given;
initial velocity of the projectile, u = 60 m/s
angle of projection, θ = 60°
time of motion, t = 5s
the vertical component of the velocity, [tex]u_y= u\ sin \theta = 60sin(60^0)[/tex]
The magnitude of the displacement after 5s is calculated as;
[tex]h = u_yt -\frac{1}{2} gt^2\\\\h = 60sin (60^0)\times 5 - \frac{1}{2} (9.8)(5)^2\\\\h = 259.81-122.5\\\\h = 137.31 \ m[/tex]
Therefore, the magnitude of the displacement after 5s is 137.31 m.
Which of the following is the best example of Newton's second law of motion?

B. An asteroid moves through space at constant velocity.
C. A baseball bat strikes a baseball.
D. A woman is sitting on a chair.
Answers
Answer:
C. A baseball bat strikes a baseball.
Explanation:
Newton's second law of motion states that acceleration happens when force is applied on the mass.
A baseball bat strikes a baseball is the best example of Newton's second law of motion because acceleration of the baseball is directly proportional to the force by which baseball bat hit it.
Hence, the correct option is 'C. A baseball bat strikes a baseball.'

rest and motion are relative terms why?
Answers
Answer:
Rest and motion are the relative terms because they depend on the observer's frame of reference. So if two different observers are not at rest with respect to each other, then they too get different results when they observe the motion or rest of a body.
At what point is the half-life of a radioactive isotope reached?
A. When half the parent nuclei in a sample have become daughter nuclei
B. When all the daughter nuclei in a sample have become parent nuclei
C. When half the daughter nuclei in a sample have become parent nuclei
D. When all the parent nuclei in a sample have become daughter nuclei
Answers
Answer:
A. When half the parent nuclei in a sample have become daughter nuclei
Explanation:
The point at which the half-life is reached is when half of the parent nuclei in a sample have become daughter nuclei.
Every radioactive atom starts with the parent. When they disintegrate they given the daughter nuclides.
The half - life is the time taken for half of the radioactive nuclei to disintegrate.
The shorter the half - life, the faster the decay process.
When the number of parents becomes half and it leads to the formation of the daughter, the half life point is attained.Answer:
A. When half the parent nuclei in a sample have become daughter nuclei

Calculate the potential energy of a roller coaster when mass is 53 kg and
height is 818 m.
10 points !
Answers
Answer:
P.E = 424869.2 Joules
Explanation:
Given the following data;
Mass, m = 53kg
Height, h = 818m
We know that acceleration due to gravity, g is equal to 9.8m/s²
To find the potential energy
P.E = mgh
Substituting into the equation, we have
P.E = 53*818*9.8
P.E = 424869.2 Joules
Therefore, the potential energy of the roller coaster is 424869.2 Joules.

Why do clouds and precipitation contain freshwater even though much of the water vapor comes from oceans and seas?
The atmosphere filters out the salt as precipitation is created
Most of the water doesn't come from the ocean, it comes from fresh water sources
Precipitation does contain 72% salt water
When water evaporates from the ocean, the salt is too dense to evaporate
Answers
Answer:
★ Most of the water doesn't come from the ocean, it comes from fresh water sources
Explanation:
Hope you have a great day :)
Most of the water doesn't come from the ocean, it comes from fresh water sources.
When water vapor in the sky condenses into droplets and hits the ground, rain is created. Although saltwater does turn into water vapor during the evaporation process, freshwater makes up the droplets that form in clouds. This is so that only the salt is left behind after the process of evaporation separates the freshwater from the saltwater.
The water vapor rises and cools, forming droplets that are virtually totally composed of freshwater when they condense.
The droplets that are heavy enough to defeat evaporation and fall as rain are the ones that make it to the earth.
Precipitation is the natural method of removing salt from water and creating fresh water.

Wave A carries more energy than wave B. Wave B must have a smaller than wave A. A. frequency B. amplitude C. wavelength D. speed
Answers
Answer:
Amplitude
Explanation:
The amount of energy a wave carries is determined by the amplitude. The larger the amplitude, the more energy the wave has, and the smaller the amplitude, the less energy the wave has.
In this case, since wave A has more energy than wave B, wave B must have a smaller amplitude than wave A.

A crane lifts a 3,000 kg beam of concrete from the ground to a height of 50m. What work is being done on the concrete?
Answers
Answer:
The work done on the concrete is 1,470,000 J
Explanation:
Given;
mass lifted by the crane, m = 3,000 kg
height through which the mass was lifted, h = 50 m
The work done on the concrete is equal to the gravitational potential energy of the concrete due to the height it was raised.
E = W = mgh
W = mgh
W = 3000 x 9.8 x 50
W = 1,470,000 J
Therefore, the work done on the concrete is 1,470,000 J
