Question: A 3-kg block is released from rest at a height h = 5m on a curved frictionless ramp as shown in Figure. The block slides

A 3-kg block is released from rest at a height h = 5m on a curved frictionless ramp as shown in Figure. The block slides down the ramp and onto a spring placed at the end of the ramp, see Figure. If the block compresses the spring a distance 90 cm before coming momentarily to rest find a) the speed of the block right before it hit the spring, b) the spring constant of the spring
