Aball is thrown horizontally from the top of a 65 m building and lands 115 m from the base of the building. ignore air resistance, and use a coordinate system whose origin is at the top of the building, with positive y upwards and positive x in the direction of the throw.
(a) how long is the ball in the air in seconds?
(b) what must have been the initial horizontal component of the velocity in m/s?
(c) what is the vertical component of the velocity just before the ball hits the ground in m/s?
(d) what is the magnitude of the velocity of the ball just before it hits the ground in m/s?
