To 40000000kg battleship Missouri accelerates from a rest in port at 2 m/s2 when a 100000 kg deck gun falls off of it. a. What is the acceleration after the gun falls off the boat? b. What is the velocity 10 seconds after the gun falls off the boat? c. What is the kinetic energy of the boat after the gun falls off the boat? Help

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.
