A 2 kg mass is attached to a spring of spring constant 20 N/m. At t = 0 the spring is at its relaxed position and the block is moving with a velocity of 4 m/s to the right. Assume the positive direction is to the right.
What is the maximum acceleration of the mass?
What is the period of mass and spring oscillation?
a spring is hanging down from the ceiling and an object of mass m is attached to the free end. the object is pulled
