On a bike, a metal chain connects the front gear sprocket to the rear gear sprocket so that the back wheel can rotate as you pedal. Suppose the front gear sprocket of your bike has a radius of 11 cm and the rear gear sprocket has a radius of 2.5 cm. As you pedal, starting from rest, the front sprocket accelerates with a constant 8.0 rad/s 2 angular acceleration for 2.5 revolutions. What is the angular velocity of the rear gear sprocket after the 2.5 revolutions

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
