A cannonball is launched horizontally with an initial velocity of 36m⋅s−1 from the edge of a cliff 200.m high. Assume that air resistance is negligible. a. Calculate the total time that the cannonball is in the air. (2) b. Determine the horizontal distance from the bottom of the cliff to where the cannonball hits the ground. (2) c. The mass of the cannonball is then doubled. State and explain whether this will affect the answer in (b). Assume launch speed is the same. (2)
