- The masses of the javelin, discus, and shot are 0.80 kg, 2.0 kg, and 7.2 kg, respectively, and record throws in the corresponding track events are about 98 m, 74 m, and 23 m, respectively. Neglecting air resistance, (a) calculate the minimum initial kinetic energies that would produce these throws, and (b) estimate the average force exerted on each object during the throw, assuming the force acts over a distance of 2.0 m. (c) Do your results suggest that air resistance is an important factor?arrow_forwardTarzan, in one tree, sights Jane in another tree. He grabs the end of a vine with length 13 pm] that makes an angle of 55° with the vertical, steps off his tree limb, and swings down and then up to Jane’s open arms. When he arrives, his vine makes an angle of 30° with the vertical. Determine whether he gives her a tender embrace or knocks her off her limb by calculating Tarzan’s speed just before he reaches Jane. Ignore air resistance and the mass of the vine.arrow_forward0.300 kgkg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.85 m/sm/s when it makes a head-on collision with a stationary 0.150 kgkgglider.

This system consists of a block of wood suspended by cords of negligible mass. When a bullet strikes the block of wood, the bullet burrows into the wood and comes to rest by frictional processes.
