Driving home from school one day, you spot a ball rolling out into the street (see the figure (Figure 1)). You brake for 1.30 s , slowing your 910-kg car from 16.0 m/s to 9.50 m/s.
a.What was the magnitude of the average force exerted on your car during braking?
b. What was the direction of the average force exerted on your car during braking?
c. What was the direction of the average force exerted on your car during braking?

11. Driving home from school one day you spot a ball rolling out into the street (Figure 5-18). You brake for 1.20 s, slowing your 950-kg car from 16.0 m/s to 9.50 m s. (a) What was the average force exerted on your car during braking? (b) How far did you travel while braking? u# 9.50 m/s v 16.0 m/s FIGURE 5-18 Problem 11 A Show your work below:
Driving to a Taylor Swift concert one day, you spot an armadillo strolling casually out into the street. You hit your brakes for 1.10 s, and your 1100 kg vehicle's speed drops from 16.0 m/s to 9.50 m/s. (a) What was the net force exerted on your car during braking? Magnitude ____________ kN Direction — backward or forward ? (b) How far did you travel while braking? ___________ m
(2 + 2 + 2 = 6 marks) While driving on highway 401 you see a traffic jam ahead. Not wanting to apply the brake, you take your foot off the gas and let the car slow down on its own. Your acceleration is -4.0 m/s2 (remember you are slowing down) and the mass of the car is 1 200 kg. a) How much frictional force acted to slow down the car? b) While slowing down, the car travels 85...
A ball rolls onto the path of your car as you drive down a quiet neighborhood street. To avoid hitting the child that runs to retrieve the ball, you apply your brakes for 1.40 s. The car slows down from that 15.0 m/s to 9.00 m/s. The mass of the car is 1140 kg. During the time the brakes were applied, what was the average force exerted on your car? How far did the car move while braking? The weight...

One billiard ball with a mass 1.20 is moving south with a speed of 4.00m/s. A second billiard ball with a mass of 0.80 kg is moving north with a speed of 5.00m/s. The balls have a glancing collision, which lasts for 6.0 ms. As a result of the collision, the first ball Is deflected by 90 degree, sending it east with a speed of 3.00 m/s. What is the velocity of...
please help!
The figure below shows a metal ball with a mass of 2.84 kg bouncing off a wall. The ball has the same speed just before and just after the impact (v - 10.0 ms, and the angle its path makes with the wall is 8 - 60.0° as shown. (Because we are analyzing the motion of the ball over a very short time just before and after Impact, you may safely ignore the effect of gravity on the...
