Bob is driving his car at 20 m/s down a hill with a slope of 5 degrees. When a deer suddenly jumps out of the woods onto the road, he slams on the brakes, and the car skids to a stop. The mass of the car is 1500 kg, and the coefficient of kinetic friction between the tires and the road is µk = 0.816. a) (3 points) Draw a free-body diagram for the car. b) (3 points) Determine the...

A bicycle and its owner roll down a hill dropping in altitude 4.0 m, ending up on level ground. The mass of the cycle plus bicyclist is 70.0 kg. We ignore the effect of friction in the first two questions. A. If the bicycle starts initially at rest, find the speed of the bicycle when it reaches level ground. B. If instead the bicycle starts with an initial speed of 4.0 m/s, find the speed of the bicycle when it...

An automobile has a mass of 2300 kg and a velocity of positive 16 m/s. It makes a rear end collision with a stationary car whose mass is 1800 kg. The cars locked bumpers and skid off together with the wheels locked. A) what is the velocity of the two cars just after the collision. B) find the impulse, magnitude and direction, the acts on the skidding cars from just after the collision until they come to a halt. C)...

A 2300 kg car moving at an initial speed of 25 m/s along a horizontal road skids to a stop in 50 m. (Note: When stopping without skidding and using conventional brakes, 100 percent of the kinetic energy is dissipated by friction within the brakes. With regenerative braking, such as that used in hybrid vehicles, only 70 percent of the kinetic energy is dissipated.) (a) Find the energy dissipated by friction. 718750 Incorrect: Your answer is incorrect. kJ (b) Find...

Th figure below shows a mass m=1.0 kg which is initially moving with speed v=6.8 m/s at the top of a frictionless hill of height h=4.4 m. It slides down the hill until it encounters a flat section with coefficient of kinetic friction µk=0.8. Find the distance D the object travels before coming to a stop.

A 1100-kg car sits at rest at the bottom of a 15 degree hill. The driver initiates the accelerator and the engine pushes it up a 15 degree hill with a net force of 4500 N parallel to the hill. There is an effective 0.1 coefficient of kinetic friction. Use energy concepts to calculate the speed of the car after it has moved 40 m along the hill’s surface.
