A 1028.0 gram mass is on a horizontal surface with μk = 0.40, and is in contact with a mass less spring with a force constant of 805.0 N/m which is compressed. When the spring is released, it does 2.58 Joule of work on the mass while returning to its equilibrium position.
Determine the distance the spring was compressed.
Find the velocity of the mass as it loses contact with spring?
