He boards his car, straps himself in and prepares for the thrill of the day. When a seagull picks an oyster up into the sky and then lets it drop on the rocks below to open the shell; where is the oyster's potential energy greatest? How much kinetic energy does it have? Where is its kinetic energy greatest? In the absence of friction such as air resistance , this amount stays constant throughout the fall. At position B, Olive is 1.

How much kinetic energy does it have? Determine the amount of cumulative work done upon Vinko's body as he crashes to a halt. Determine the total mechanical energy of the ball upon hitting the floor on the opponent's side of the net. An instant before striking the ground, how much mechanical energy â€” rounded to the nearest joule â€” does the particle have? He leaves the springboard from a height of 3. You should complete 35 question in 45 minutes. He slides down the 32-degree incline and across the plateau at its base. Detailed solutions to the 2016 free- response questions.

Because friction is not present, start with the standard conservation-of-mechanical-energy formula: where E represents the total mechanical energy, U is the potential energy entirely gravitational in this problem , and K is the kinetic energy. He spots a police car with a radar gun and quickly slows down to a legal speed of 20. The initial location i is point A, and the final location f is point D. Round your answer to the nearest tenth of a meter per second. Determine the change in potential energy of Vinko from the top of the hill to the point at which he stops.
