SLIDING OSCILLATIONS 3 My Notes A block weighing 273 g slidesalong a frictionless track at a speed 8.9 cm/s. It then attaches toa spring-bumper with an electromagnetic device so that the blockattaches to the bumper. The bumper has a mass of 115 g, and thespring has a stiffness of 1110 kg/s2 and an equilibrium length of9.5 cm. After the spring compresses and returns to its originallength, the magnet turns off and the block launches off again,conserving energy. (a) How fast is the block just after it attachesto the paddle? (b) What is the maximum compression of the springbefore the block turns around? (b) How fast is the block movingafter it launches off the paddle?
