The mass of a hoop of radius 1.2 m is 6.7 kg. It rolls without slipping across a horizontal surface with a speed of 10.2 m/s. (a) How much work (in J) is required to stop the hoop? (b) If the hoop rolls without slipping up a surface at 40° to the horizontal with an initial speed of 10.2 m/s, how far along the incline will it travel (in m) before stopping and rolling back down?
