5. The driver of a car travelling 75.0 km/hr suddenly sees road construction up ahead. She takes 2.30 s to begin applying the brakes. The car slows down at a constant rate of 10.0 km/br's for until she comes to a stop. a. Draw a picture showing the various intervals of the car's motion and accelerations, b. Calculate the average acceleration of the car after the driver applies the brake c. What is the total distance the car travelled from...

Driving down the road at a speed of 26.6 m/s, you suddenly notice a fallen tree blocking the road a distance of 57.9 m ahead of you. You step on the brake pedal and decelerate at a constant rate. What must the magnitude of your acceleration be so that you will come to a stop 7.6 m in front of the tree?

Driving down the road at a speed of 40.0 m/s, you suddenly notice a fallen tree blocking the road a distance of 88.4 m ahead of you. You step on the brake pedal and decelerate at a constant rate. What must the magnitude of your acceleration be so that you will come to a stop 5.9 m in front of the tree?

9. A car driving on the highway has a mass M and a velocity v. A truck on the highway has a mass 2M. If the truck has the same velocity v as the car, how does the momentum of the truck compare to the momentum of the car? a. b. If the truck as the same momentum as the car, how does the velocity of the truck compare to the velocity of the car *Now, assume the truck is...

The driver of a car of mass M which is moving along a straight road with initial speed v0 sees a deer in her headlights, and reacts quickly, lifting her foot of the gas and applying the brake pedal with maximum force. The anti-lock brakes cause the largest possible static friction force to be applied on the tires by the road, which continue to roll so the car does not skid. The coefficient of static friction between the tires and...

65 mi/h suddenly (13%) Problem 7: On notices a truck 0.15 mi in front of him. That truck is moving in the same direction at v2 31 mi/h. In order to avoid a collision, the person has to reduce the speed of his car to v2 during time interval Δ. The smallest magnitud of acceleration required for the car to avoid a collision is a. During this problem, assuhme the direction of motion of the car is positive direction. Refer...

1 pts You are driving on a straight road at exactly 31.0 miles per hour when you see a child run out in front of your car, chasing a ball. You push the brakes hard, which results in an acceleration of exactly -36000 miles/hour2. The child freezes in panic and you cannot swerve to avoid the child because there are cars parked on both sides of the street. How many feet does your car travel before it comes to a...
