Posted by Harold on Monday, March 16, 2009 at 7:37pm.

A block of weight 3.8N is launched up a 30 degree inclined plane of length 2.25m by a spring with spring constant 2.35kN/m and maximum compression 0.10m. The coefficient of kinetic friction is 0.50. How much kinetic energy does it have at the top of the incline?

I get 2.4J am I wrong, if so please help in showing hoe this process woorks out. It would be much appreciated.
