A wizard places cannon on the surface of the distant planet that consists of the gravitational Force of half of earth's. A ball of 50 kg is fired from the cannon at 48 degrees from the horizontal. The ball arrives at a height of 255m. Compute the magnitude of the initial velocity of the ball, the time it spends in the air, and determine how far the ball travels horizontally. Now assume that the wizard then decreases the gravity to a fourth of that of earths and consists of the ball fired at an angle of 60 degrees from the horizontal. Determine how much higher would it travel if it were fired from the similar initial velocity?
