Find L, the distance traveled along the incline by the block after it exitsthe gun. Ignore friction when the block is inside the gun. Also, assume that the uncompressed spring is just at the top of the gun(i. e., the block moves a distance x_c while inside of the gun). Use gfor the magnitude of acceleration due to gravity.
Express the distance L in terms of x_c, k, m,g, mu, and theta.
