A player passes a 0.600 kg basketball downcourt for a fast break. The ball leaves the player's hands with a speed of 8.30 m/s and slows down to 7.20 m/s at its highest point. A) Ignoring air resistance, how high above the release point is the ball when it is at its maximum height? B) How would doubling the ball's mass affect the result in part (a)?

Froghopper insects have a typical mass of around 13.1 mg and can jump to a height of 45.8 cm. The takeoff velocity is achieved as the insect flexes its legs over a distance of approximately 2.00 mm. Assume that the jump is vertical and that the froghopper undergoes constant acceleration while its feet are in contact with the ground. Ignore air resistance. What is the acceleration of the insect during the time of the jump (before it leaves the ground)?...

The drawing below shows a person who, starting from rest at the top of a cliff, swings down at the end of a rope, releases it, and falls into the water below. There are two paths by which the person can enter the water. Suppose he enters the water at a speed of 13.5 m/s via path 1. How fast is he moving on path 2 when he releases the rope at a height of 4.15 above the water? Ignore...

1) A 67-kg base runner begins his slide into second base when he is moving at a speed of 3.7 m/s. The coefficient of friction between his clothes and Earth is 0.70. He slides so that his speed is zero just as he reaches the base. (a) How much mechanical energy is lost due to friction acting on the runner? (b) How far does he slide? 2) A running 53-kg cheetah has a top speed of 31 m/s. (a) What...
