A 0.095-kg dodge ball is traveling at 22 m/s along the concrete ground. Friction with a magnitude of 0.75 N is exerted on the moving ball by the surface of the concrete. Someone also uses their foot to slow the motion of the ball to a stop. If the ball travels 0.20 m before stopping, then determine the amount of force applied to the ball by the foot.

Asolid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. the cylindrical shell has light-weight spokes connecting the shell to the axle. a rope is wrapped around each cylinder and tied to blocks of equal masses that are held the same height above the ground. both blocks are released simultaneously. the ropes do not slip. which block hits the ground first? or is it a tie?
