Abasketball of mass 0.55 kg is dropped from rest from a height of 1.22 m. it rebounds to a height of 0.40 m.
(a) how much mechanical energy was lost during the collision with the floor? j
(b) a basketball player dribbles the ball from a height of 1.22 m by exerting a constant downward force on it for a distance of 0.13 m. in dribbling, the player compensates for the mechanical energy lost during each bounce. if the ball now returns to a height of 1.22 m, what is the magnitude of the force?

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
