1. A block with a mass of 10kg is initially at rest while held in contact with a compressed spring. The spring has a stiffness constant of 2000 N/m and is initially compressed by a length of 0.4 meters. Once the mass leaves the spring it will slide 1 meter across the surface of a table where 0.3 is the coefficient of kinetic friction. There are no frictional losses while the mass is in contact with the spring, and there are no losses due to air resistance. Only losses are due to the interaction with the table during the 1-meter slide. The surface of the table is 2 meters above the floor.

A 51-kg box is being pushed a distance of 7.0 m across the floor by a force P→⁢ whose magnitude is 185 N. The force P→⁢ is parallel to the displacement of the box. The coefficient of kinetic friction is 0.21. Determine the work done on the box by each of the four forces that act on the box. Be sure to include the proper plus or minus sign for the work done by each force.
A 0.053 kg bullet is fired into a 5.38 kg wood block, which is attached to a pendulum. At the instant after they collide inelastically, the total mechanical energy of the system is 24.1 J. At the top of the swing of the pendulum, the block and bullet have risen to a maximum height, h, and now have a velocity of v = 0 m/s Use conservation of energy to find the maximum height, h, of the block + bullet system. Hint: The following formula will be useful PE = mx9.8×h %3D
A cart of mass 0.72 kg is attached to one end of of a spring and placed on a low-friction track, inclined at an angle of 56.0 degrees with respect to the horizontal. The cart is found to be in equilibrium when the spring is stretched to a total length of 44.8 cm. Given that the rest length for the spring is 12.8 cm, what is the spring constant for the spring?
A horizontal spring with stiffness 0.8 N/m has a relaxed length of 16 cm (0.16 m). A mass of 22 grams (0.022 kg) is attached and you stretch the spring to a total length of 29 cm (0.29 m). The mass is then released from rest. What is the speed of the mass at the moment when the spring returns to its relaxed length of 16 cm (0.16 m)? m/s
