Abowling ball traveling with constant speed hits the pins at the end of a bowling lane 16.5 m long. the bowler hears the sound of the ball hitting the pins 2.50 s after the ball is released from his hands. what is the speed of the ball? the speed of sound is 340 m/s.

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
