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...
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 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...

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?

020 (part 1 of 3) 10.0 points You are driving at the speed of 34.8 m/s (77.862 mph) when suddenly the car in front of you (previously traveling at the same speed) brakes and begins to slow down with the largest deceleration possible without skid- ding. Considering an average human reaction, you press your brakes 0.576 s later. You also brake and decelerate as rapidly as possible without skidding. Assume that the coefficient of static friction is 0.722 between both...

To visit your favorite ice cream shop, you must travel 490 m west on Main Street and then 940 m south on Division Street. Suppose you take 46 s to complete the 490-m displacement and 74 s to complete the 940-m displacement. What is the magnitude of your average velocity during this 120-second period of time? What is the direction of your average velocity during this 120-second period of time? What is your average speed during the trip?
