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

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...

A soccer ball of mass 0.36 kg is rolling with velocity <0, 0, 1.5> m/s, when you kick it. Your kick delivers an impulse of magnitude 2.7 N.s in the -x direction. The net force on the rolling ball, due to the air and the grass, is 0.34 N in the direction opposite to the direction of the ball's time 1.5 s after you kick it, assuming that the ball is at the origin at the moment it is kicked....

A soccer ball of mass 0.39 kg is rolling with velocity <0, 0, 2.4> m/s, when you kick it. Your kick delivers an impulse of magnitude 2.4 N·s in the -x direction. The net force on the rolling ball, due to the air and the grass, is 0.32 N in the direction opposite to the direction of the ball's momentum. Using a time step of 0.5 s, find the position of the ball at a time 1.5 s after you...

(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 soccer ball of mass 0.50 kg is rolling with velocity 0, 0, 1.8 m/s, when you kick it. Your kick delivers an impulse of magnitude 1.2 N · s in the −x direction. The net force on the rolling ball, due to the air and the grass, is 0.22 N in the direction opposite to the direction of the ball's momentum. Using a time step of 0.5 s, find the position of the ball at a time 1.5 s...

You are driving through town at 12.0 m/s when suddenly a ball rolls out in front of you. You apply the breaks and begin decelerating at 3.5 m/s^2. How far do you travel before stopping. when you only travel only half the distance is your speed 6.0 m/s, greater than 6.0 m/s or less than 6.0 m/s. Find the speed of your car when you have traveled half the distance?

You are observing the poles along the side of the road. You have already stopped and measured the distance between adjacent poles as 41.1 m. You are now driving again and have activated your smartphone stopwatch. You start the stopwatch at t = 0 as you pass pole #1. At pole #2, the stopwatch reads 10.3 s. At pole #3, the stopwatch reads 26.8 s. Your friend tells you that he was pressing the brake and slowing down the car...
