A 0.25 kilogram shoe is thrown out a window during a physics class. The shoe attains an acceleration of 9.8 m/s ^ 2 before hitting an unsuspecting individual standing on a sidewalk. How much force (in Newtons) did the shoe hit with?

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?
