Question

SLIDING OSCILLATIONS 3

A block weighing 408 g slides along a frictionless track at a speed 5.9 cm/s. It then attaches to a spring-bumper with an electromagnetic device so that the block attaches to the bumper. The bumper has a mass of 163 g, and the spring has a stiffness of 1820 kg/s² and an equilibrium length of 10.2 cm. After the spring compresses and returns to its original length, the magnet turns off and the block launches off again, conserving energy.

(a) How fast is the block just after it attaches to the paddle?

(b) What is the maximum compression of the spring before the block turns around?

(c) How fast is the block moving after it launches off the paddle?
