a block (m=0.0433 kg) is sitting on a frictionless horizontal surface. The mass is connected to a spring with a spring constant of 24.5 N/m. The block is pulled back released from rest. The maximum acceleration of the block is 31.5 m/s^2. A. Determine the amplitude of the motion. B. Determine the speed of the block when the spring is compressed by 0.0452 m.
