Block Sliding into Spring A block of mass m = 5.5 kg is released from rest at a height of H = 3.0 m on a curved frictionless ramp. At the foot of the ramp is a spring whose spring constant is k = 200.0 N/m. What is the maximum compression of the spring, x? 1.27 m After the spring reaches its maximum compression, it pushes the block backwards. What is the maximum height reached by the block?
