Answer:
A) I = 20 N s
, B) F = 7.92 N
Explanation:
A) The momentum is
I = F Δt
calculate
I = 50 0.40
I = 20 N s
B) The momentum is related to the change of the moment of the system
I = Δp
F Δt = m [tex]v_{f}[/tex] - m v₀
in this case we must assume that the initial velocity is very small, vo = 0
F = m v_{f} / Δt
calculate
F = 0.11 36 / 0.5
F = 7.92 N

A rock tumbles straight down from a cliff, it is moving at 20 m/s when it hits. What is the height of the cliff? The mass of the rock is 8 kg.
A. 400 m
B. 160 m
C. 2.5 m
D. 20.4 m
Answers
Answer:
D. 20.4m
Explanation:
assuming there is no initial velocity, where v=final velocity, g=acceleration due to gravity, and t=time
v = g*t
20 = 9.8*t
t =2.03 s
y = (1/2) g t^2 where y=vertical distance, g=acceleration due to gravity, and t=time
y = 4.9 (2.03)^2
y = 20.4 meters

a rope is used to pull a 2.89kg bucket of water out of a deep well. what is the acceleration of the bucket when the tension in the rope is 30.2N?
Answers
Answer:
Explanation:
Tension in the rope in upward direction = 30.2 N .
weight of bucket in downward direction = mg
net force in upward direction = 30.2 - mg
30.2 - 2.89 x 9.8
= 1.878 N
acceleration = net force / mass
= 1.878 / 2.89
= .65 m /s² .
= 65 cm /s²
The acceleration of the bucket will be "65 cm/s²".
Tension and acceleration:Whenever the rope, thread, or cable is expanded underneath an applied force, a force is created in that as well, is a tension force.
Tension acts anywhere along the lengths of the string throughout the opposing directly proportional to the force acting upon that.
According to the question,
Tension in the rope = 30.2 N
Mass of bucket, m = 2.89 kg
Acceleration due to gravity, g = 9.8
Now,
The net force will be:
= Tension - mg
= [tex]30.2-(2.89\times 9.8)[/tex]
= [tex]1.878[/tex] N
hence,
The acceleration of the bucket be:
= [tex]\frac{Net \ force}{Mass}[/tex]
By substituting the values,
= [tex]\frac{1.878}{2.89}[/tex]
= [tex]0.65[/tex] m/s²
or,
= [tex]65[/tex] cm/s²
Thus the above approach is correct.

Two men pull a 31 kg box with forces 11.6 N and 7.6 N in opposite directions. Find the resultant
acceleration of the box. (Hint: Find the net force first)
Answers
Answer:
0.13 m/s².
Explanation:
Mass (m) of box = 31 kg
Force 1 (F1) = 11.6 N
Force 2 (F2) = 7.6 N
Acceleration (a) of box =?
Next, we shall determine the net force acting on the box. This can be obtained as follow:
Force 1 (F1) = 11.6 N
Force 2 (F2) = 7.6 N
Net force (Fn) =?
Fn = F1 – F2
Fn = 11.6 – 7.6
Fn = 4 N
Thus, the net force acting on the box is 4 N.
Finally, we shall determine the acceleration of the box as follow:
Mass (m) of box = 31 kg
Net force (Fn) = 4 N
Acceleration (a) of box =?
Force (F) = mass (m) × acceleration (a)
4 = 31 × a
Divide both side by 31
a = 4 / 31
a = 0.13 m/s²
Therefore, the resultant acceleration of the box is 0.13 m/s².

Which resultant force is NOT possible if 50 N force and a 60 N force act concurrently?
Answers
Answer:
The options are not shown, so i will answer in a general way.
Suppose the case where the forces act in opposite directions, then we need to subtract the forces, and we know that the magnitude of the resultant force will be:
60N - 50N = 10N
Now, suppose the case where both forces act in the exact same direction, in that case, we will add the forces to get:
60N + 50N = 110N
Then the only range of forces that we can get in this system, are the forces such:
10N ≤ F ≤ 110N
Any resultant force outside that range is not possible in this situation.

I would say A because Newton Law of motion is you pushing force and the object pushing force back on you
A basketball sitting on the basketball court doesn’t move until something pushes it. - this provides the best evidence for Newton’s First Law of Motion. Hence, option (B) is correct.
What is Newton’s First Law of Motion?According to Newton's first law of motion: Until and unless an external force occurs on a body, it is in a condition of rest or uniform motion in a straight line.
According to Newton's first law of motion, a body won't begin to move unless and until an outside force acts on it. When anything starts moving, it won't stop or vary its speed unless another force acts on it. The law of inertia is another name for the first law of motion.
Hence, a basketball sitting on the basketball court doesn’t move until something pushes it. This is an example of Newton’s First Law of Motion.

A chunk of ice with a mass of 1.2 kg melts and absorbs 3.33 x 10³J of energy. Which best describes what has happened in this system?
Answers
Answer:
- Its entropy increases.
Explanation:
Entropy is defined as a 'measure of the amount of energy in a physical system that cannot be used to do work.' It is also employed to denote randomness, disorder, or uncertainty of the arrangement/system. In the given system, the melting of ice denotes the 'increase in entropy' as the amount of energy unavailable to do work increases('absorbs 3.33 x 10³J of energy'). Thus, this signifies that the entropy increases with a rise in temperature as it allows the substance to have greater kinetic energy.
