1. A block of mass m is placed in a smooth-bored spring gun at the bottom of the incline so that it compresses the spring by an amount x. The spring has spring constant . The incline makes an angle (theta) with the horizontal and the coefficient of kinetic friction between the block and the incline is mew. The block is released, exits the muzzle of the gun, and slides up an incline a total distance L.

2. Energy equations

3. I keep getting ;

((.5(k*x^2))/((m*g*sin(theta)+(mew*m*g*cos(theta)))+x

-- This answer is wrong and i don't understand why, I've worked it like 5 times and always get this answer. Please Help!
