A 4 kg ball is thrown from 6 m tall building (point A) at initial vilocity 28 m/s. As shown in the figure, the ball settled at point B on top of another building with a height of 15 m above the ground . Ignoring air resistance, what is the velocity of the ball just before it strikes the top bf the other building at point B? h2- 36.6 m/s O 33.6 m/s O 24.6 m/s O 18.6 m/s O 196 m/s

A carnival game has you throw a ball through a hoop as the hoop falls from some height. Suppose for onesuch game the hoop falls from a height of 2.0 m above your hand when you throw the ball, and you stand ahorizontal distance of 3.0 m away. If you throw the ball right when the hoop is released (from rest), at whatangle must you throw the ball in order for you to win the prize?

A circus performer stands on a platform and throws an apple from a height of 37.0 m above the ground with an initial velocity vo as shown in the figure below. A second, blindfolded performer must catch the apple. If vo = 30.0 m/s, how far from the end of the platform should the second performer stand? (Assume 0 = 35.0°.) Your response differs from the correct answer by more than 100%. m Vo ?-
