    Two cars are traveling in the same lane in the same direction. They are 120 ft apart and are both traveling at 60 mph. The roadway is level. The leading car hits a disabled milk truck and comes to an instatenous stop. The perception-reaction time of the driver in the trailing car is ½ second. The driver of the trailing car locks the brakes and skids into the lead car. The coefficient of friction between the roadway and skidding tires...

    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...

    It requires a stopping distance of 150 m to brake on a flat road from a speed of 22 m/s to rest with a particular set of brakes. (a) Find the acceleration of the car. (b) Find the coefficient of friction between the tires and the road. (You may assume the car has a mass of 1250 kg but that is NOT needed to solve the problem.)

    24) How much work is performed by friction in slowing a 10kg object from 4 m/s to 2 m/s? 25) To avoid an accident, you slam on your brakes, skidding for a distance of 40 m before you stop. (Your anti-lock brakes were malfunctioning!). Assuming a coefficient of kinetic friction of 0.8 between your tires and the road, how fast were you going before slamming on the brakes? 26) A 1-kg block is held below a vertically mounted spring -...

    A 1500-kg car starts from rest and accelerates uniformly to 18.0 m/s in 12.0 s over a dry concrete road. Assume that kinetic friction remains constant at 400 N during this time. – (a) Find the net work done on the car and the work done by the engine. – (b) How many revolutions does each tire make over the 12.0 s interval? What is the angular speed of the wheels when the car has traveled half the total distance?...

    5) (10 pts) John is baby-sitting Casey, his 3-year old brother. He puts a crash helmet on Casey, places him in the red wagon and takes him on a stroll through the neighborhood. As John starts across the street, he exerts a 58 N forward force on the wagon. There is a 20 N resistance force (friction) and the wagon and Casey have a combined weight of 302 N.
