When Marie sees the red traffic light, Marie brakes to a halt from a speed of 70 m/s in just 2 seconds. What is her deceleration?
Answers
Answer:
-35 [tex]m/s^2[/tex]
Explanation:
Deceleration is the complete opposite of acceleration and is calculated by adding a negative sign to the formula for finding acceleration.
Since acceleration is calculated by diving the change in velocity with time, deceleration will become:
Deceleration = -Δv/t, where Δv = change in velocity and t = time
In this case, Δv = 70 m/s and t = 2 s, hence;
Deceleration = -70/2 = -35 [tex]m/s^2[/tex]
The deceleration is 35 [tex]m/s^2[/tex].

What is the sum of the forces in an action reaction pair?
А. always less than zero
B. always greater than zero
C. always equal to zero
D. sometimes less than zero
Answers
Answer:
C.
Explanation:
For every action there is a opposite negative reaction. So what ever the positive action is there is the negative reaction for it.
For example: +10 action and -10 reaction. It will always equal 0. If it doesn't then you probably might have done something wrong.
Answer:
always equal to zero
1. How are velocity, time, and acceleration
related mathematically?
Answers
velocity-time. The relation between velocity and time is a simple one during uniformly accelerated, straight-line motion. The longer the acceleration, the greater the change in velocity. Change in velocity is directly proportional to time when acceleration is constant.

which si unit whould be most appropriate for describing the length of a shoe?
0.kilometers
0.milimeters
0.milliliters
0.kilomgrams
can u asnswer fast im with my teacher plz
Answers
Answer:
Milimeters
Explanation:
This kind of question must be checked with everyday elements, in this way we will analyze each of the options until we reach the appropriate:
kilograms can not be because this unit serves to measure the mass not the length.
kilometers (km) is a unit of length, but however it does not serve for this measurement since a km is equivalent to 1000 meters, therefore measuring the length of a shoe with a ruler measuring 1000 meters is very impractical.
milliliters is a unit of volume, and can often be found in the measurement of volume content of liquids, for example 700 milliliters of milk or 1000 milliliters of water. Therefore it is impractical to measure a shoe with a unit of volume.
In this way the way to measure a shoe correctly is using a ruler or measuring instrument graduated in millimeters.

A psychopathologist records the number of criminal offenses among teenage drug users in a nationwide sample of 1,201 participants. To measure the variance of criminal offenses, he computes SS = 10,800 for t his sample. Compute the standard deviation.
Answers
Answer:
Standard deviation = 3
Explanation:
Given
[tex]N = 1201[/tex]
[tex]SS = 10800[/tex]
Required
Determine the standard deviation
First, we need to determine the variance;
[tex]Variance = \frac{SS}{N - 1}[/tex]
This gives:
[tex]Variance = \frac{10800}{1201 - 1}[/tex]
[tex]Variance = \frac{10800}{1200}[/tex]
[tex]Variance = 9[/tex]
Know that:
[tex]Variance = SD^2[/tex]
Where SD represents standard deviation
This gives
[tex]9 = SD^2[/tex]
Take square root
[tex]SD = \sqrt 9[/tex]
[tex]SD = 3[/tex]

A car accelerates uniformly in a straight line
from rest at the rate of 3.7 m/s2.
What is the speed of the car after it has
traveled 63 m?
Answer in units of m/s
Answers
Answer:
21.59 m/s
Explanation:
recall that one of the equations of motions can be expressed as
v² = u² + 2as
where,
v = final velocity (we are asked to find this)
u = initial velocity = 0m/s (because it says that it starts from rest)
a = acceleration = 3.7m/s²
s = distance travelled = 63 m
simply substitute the known values above into the equation:
v² = u² + 2as
v² = 0² + 2(3.7)(63)
v² = 466.2
v = √466.2
v = 21.59 m/s

Which statement can be supported by using a position-time graph?
A negative slope results when an individual is moving away from the origin.
A horizontal line on the graph means the individual is moving at a non-zero velocity.
A positive slope results when an individual is moving away from the origin.
The speed of an individual cannot be determined from this type of graph.
Column A should be “Time,” and Column B should be “Position.”
Column A should be “Position,” and Column B should be “Time.”
Column A should be “Velocity,” and Column B should be “Speed.”
Column A should be “Speed,” and Column B should be “Velocity.”
Answers
Answer:
Explanation:
Think about the equation for velocity. Its the change in position over the change in time. And now think about the formula for slope, its the change in y over the change in x. Now, if you have a position vs time graph, the slope is position over time, the direct formula for velocity. Therefore, the slope of a position vs time graph gives the velocity in that interval. You could take the derivative at that point and get the instantaneous velocity.
In the first argument, the only way to get a negative slope is if youre moving to the left of your initial position as you pass through time. So the claim isnt necessarily true. When you move away from the origin, that simply means youre moving through time.
In the second argument, a horizontal slope means the value is 0. That means there is a value of 0 for your velocity, aka standing still.
In the third argument, a positive slope means youre moving to the right of your initial position as you go through time.
The fourth one is incorrect. Speed is the magnitude of velocity, and the slope can be determined an any point besides vertical slopes, which would require time to literally stop.
I dont understand the very last part of what you posted, so try to make a decision based on what I just explained to you
Answer:
The answer should be
"A positive slope results when an individual is moving away from the origin."
