A tennis ball of mass (75 g) is placed on top of a basketball of mass (590 g), both balls are freed from rest and at the same time fall to a height of (1.2 m) as shown in the figure. Calculate the speed of the basketball when it reaches the ground. Assuming that the collision is elastic with the ground, calculate the height that the tennis ball reaches.

Starting from rest, a small block of mass m = 0.25 kg slides down an incline from a height h = 1.2 m. As it slides down, the block experiences a force of kinetic friction of constant magnitude fk = 2.1 N only over a distance L = 0.2 m, as shown in the figure. The incline is frictionless everywhere else. After reaching the bottom of the incline, the block strikes a larger block of mass M = 1.8 kg that is attached to a spring of spring constant k = 6.5 N/m. The large block was originally at rest. The blocks stick together upon impact and travel together on the frictionless horizontal surface. Assume that both blocks are subject to the regular force of gravity (g = 9.80665 m/s2). (a) Determine the speed of the small block right before it collides with the larger block. Answer: m/s (b) Determine the speed of the combination of the two blocks immediately after the collision. Answer: m/s (c) Determine the compression of the spring when the combination of the two blocks comes to rest. Answer: m

Consider a frictionless track as shown in the figure below. A block of mass m1 = 2.00 kg is released from point (A) from a height of h = 1.15 m. It makes a perfectly inelastic collision at point (B) with a block of mass m2 = 2.00 kg that is initially at rest. After the collision, the block of mass m2 moves to the right and collides with a spring at point ( C . The spring is attached to a wall and has a spring constant of 8.59 kN/m. (a) Calculate the energy loss during the collision. Enter the magnitude. J (b) Calculate the maximum compression of the spring. cm (c) Instead of an inelastic collision, consider a head-on elastic collision at point B. During this specific elastic collision when the masses are equal, m1 transfers its kinetic energy to m2 and as a result, m1 comes to rest. Calculate the maximum compression of the spring. cm
