Homework Help: work and energy(physics)

Posted by Anonymous on Friday, November 2, 2012 at 1:24am.

A mass m = 12.0 kg rests on a frictionless table and accelerated by a spring with spring constant k = 4597.0 N/m. The floor is frictionless except for a rough patch. For this rough path, the coefficient of friction is μk = 0.49. The mass leaves the spring at a speed v = 3.8 m/s.
