A student fires a cannonball diagonally with a speed of 38.0m/s from a height of 58.0m as shown. Neglect drag. Determine all unknowns and answer the following questions. How long did the ball rise? unit What was the ball's maximum height above the ground? unit How long did the ball remain in the air? unit How far from the base of the building did the ball land? unit How fast was the ball moving as it struck the ground? unit At what angle (with the horizontal) did the ball land? Calculate the magnitude of the angle between the final velocity vector and the nearest horizontal Answers should be between 0 and 90. unit 74.0
