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.

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
