Exercise 101

Avg difficulty 2.5

A mass of 22 kilograms is on a spring with spring constant kk newtons per meter with no damping. Suppose the system is at rest and at time t=0t=0 the mass is kicked and starts traveling at 2 meters per second. How large does kk have to be so that the mass does not go further than 3 meters from the rest position?
