Answer #1

A block of mass m = 0.53 kg attached to a spring with force
constant 119 N/m is free to move on a frictionless, horizontal
surface as in the figure below. The block is released from rest
after the spring is stretched a distance A = 0.13 m. (Indicate the
direction with the sign of your answer. Assume that the positive
direction is to the right.)

A horizontal spring attached to a wall has a force constant of
760 N/m. A block of mass 1.30 kg is attached to the spring and
oscillates freely on a horizontal, frictionless surface as in the
figure below. The initial goal of this problem is to find the
velocity at the equilibrium point after the block is released.
