0.250 kg block attached to a light spring oscillates on a frictionless, horizontal table. The oscillation amplitude is A = 0.125 m and the block moves at 3.00 m/s as it passes through

equilibrium at x = 0.

(a) Find the spring constant, k.

(b) Calculate the total energy of the block- spring system.

(c) Find the block’s speed when x = A/2.​
