How far was the spring stretched from its unstreched length

Reference no: EM13542448

A mass m = 12.0 kg rests on a frictionless table and accelerated by a spring with spring constant k = 4827.0 N/m. The floor is frictionless except for a rough patch. For this rough path, the coefficient of friction is ?k = 0.41. The mass leaves the spring at a speed v = 3.3 m/s.

1) How much work is done by the spring as it accelerates the mass?
2) How far was the spring stretched from its unstreched length?
