A block, no friction, of 1 kg is attached to a spring rests on a horizontal surface with a length L. The spring is connected to a fixed point. The 1kg block is kicked and has a velocity of 1 m/s. As the block swings around the fixed point, the spring stretches to a total distance of L + x, at position 90 degrees counter-clockwise from rest.. What is the distance in meters the spring stretches? L=1m m=1kg k=1 N/m Vi=1 m/s x=? F=-kx I am having a difficult time getting this problem started. Thanks!
