Aball of radius r rolls on the inside of a track of radius r. if the ball starts from rest at the vertical edge of the track, find an expression for its speed (using terms g, r, and r) when it reaches the lowest point of the track, rolling without slipping? do not assume that the ball radius r is small in comparison to the track radius, r.

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
