Compute all parts of given problem:
Problem: A block of mass 1.6 kg is attached to a horizontal spring that has a spring constant k of 1 x 103 N/m. The spring is compressed 2.0 cm and is then released from rest on a frictionless surface.
Part A: Calculate the speed and elastic potential energy of the block as it passes through the equilibrium position x = 0. (Elastic potential energy means potential energy associated with a stretched or compressed spring.)
Part B: Calculate the speed and elastic potential energy of the block when it is in the position x = 1.1 cm.
Please show solution step by step with details. Thanks.
