HELP Me please exammss?
A 0.24-kg block on a horizontal frictionless surface is attached to an ideal massless spring whose spring constant is 310 N/m. The block is pulled from its equilibrium position at x = 0.00 m to a displacement x = +0.080 m and is released from rest. The block then executes simple harmonic motion along the horizontal x-axis. When the displacement is x = 2.6×10−2 m, what is the kinetic energy of the block?
