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...

A car’s bumper is designed to withstand a 3.0–km/h (0.833–m/s) collision with an immovable object without damage to the body of the car. The bumper cushions the shock by absorbing the force over a distance. Calculate the magnitude of the average force on a bumper that collapses 0.220 m while bringing a 880–kg car to rest from an initial speed of 0.833 m/s.

Coriolis' alternative method for finding work can be used to estimate the relative stopping distance for a car given the car's speed. For this application of Coriolis' alternative method, the force of friction is in the opposite direction of the motion of the car on which that frictional force is acting, and the "work required to stop the car" (sometimes called "the work done by friction") is equivalent to the amount of mechanical energy converted to thermal energy by the...

A uniform cylindrical turntable of radius 1.70 m and mass 29.1 kg rotates counterclockwise in a horizontal plane with an initial angular speed of 4π rad/s. The fixed turntable bearing is frictionless. A lump of clay of mass 2.31 kg and negligible size is dropped onto the turntable from a small distance above it and immediately sticks to the turntable at a point 1.60 m to the east of the axis. (a) Find the final angular speed of the clay...
