One end of a spring is attached to a solid wall while the other end just reaches to the edge of a horizontal, frictionless tabletop, which is a distance h above the floor. A block of mass M is placed against the end of the spring and pushed toward the wall until the spring has been compressed a distance X, as shown above. The block is released, follows the trajectory shown, and strikes the floor a horizontal distance D from the edge of the table. Air resistance is negligible. Determine the time elapsed from the instant the block leaves the table to the instant it strikes the floor.
A recently patented pile driver pounds piles into the ground by launching 15 kg bowling balls from a spring loaded gun, up around a frictionless loop-de-loop of radius r= 8 m, and down onto the pile. When the spring is compressed by As = 2 m, the bowling balls have a speed of 20 m/s at the top of the loop, as shown. (You may v = 20 m/s r=8 m assume g = 10 m/s².) k ?

If R = 22.3 cm, M = 275 g, and m = 108 g in the figure, find the speed of the block after it has descended 12.9 cm starting from rest. Solve the problem using energy conservation principles.
1. A 5.00-kg block is set into motion up an inclined plane with an initial speed of v; = 8.00 m/s. The block comes to rest after traveling 3.00 m along the plane, which is inclined at an angle of 30.0° to the horizontal. For this motion determine (a) the change in the block's kinetic energy, (b) the change in the potential energy of the block- Earth system, and (c) the friction force exerted on the block (assumed to be constant). (d) What is the coefficient of kinetic friction?

I am unsure where to start on this problem how do I do it?
Is it possible for a friction force to increase the total mechanical energy of a system? If so, give examples.
Is it possible for the total mechanical energy of a moving particle to be negative? No, because a moving particle has positive kinetic energy. Only if friction is involved. No, because potential energy cannot have a value more negative than the value of the positive kinetic energy of the particle. yes
