You throw a 0.374 kg ball off the top of a 13.0 m tall building with an initial angle of 30.0∘ above the horizontal. The ball rises to a maximum height of 18.6 m before falling back to the ground. How much work does gravity do on the ball from the point you release the ball until it hits the ground? 47.6 J −47.6 J −68.2 J 68.2 J

In the figure, a small block of mass m = 0.023 kg can slide along the frictionless loop-the-loop, with loop radius R = 13 cm. The block is released from rest at point P, at height h = 6.1R above the bottom of the loop. (a) How much work does the gravitational force do on the block as the block travels from point P to point Q? J (b) How much work does the gravitational force do on the block as the block travels from point P to the top of the loop? J If the gravitational potential energy of the block-Earth system is taken to be zero at the bottom of the loop, find the following. (c) the potential energy when the block is at point P J (d) the potential energy when the block is at point Q (e) the potential energy when the block is at the top of the loop J (f) If, instead of being released, the block is given some initial speed downward along the track, do the answers to (a) through (e) increase, decrease, or remain the same? increase decrease remain the same

A small glider is placed against a compressed spring at the bottom of an air track that slopes upward at an angle of 48.0∘ above the horizontal. The glider has mass 9.00×10−2 kg. The spring has 680 N/m and negligible mass. When the spring is released, the glider travels a maximum distance of 1.50 m along the air track before sliding back down. Before reaching this maximum distance, the glider loses contact with the spring. Part A What distance was the spring originally compressed? Express your answer in meters. Part B When the glider has traveled along the air track 0.500 m from its initial position against the compressed spring, is it still in contact with the spring? Yes No Submit Request Answer Part C What is the kinetic energy of the glider at this point? Express your answer in joules.
