A man throws a ball straight upward with speed 30 m/s from the top of a building that is 75 m high. Ignore air resistance and choose the vertical y-axis to be positive downward with origin at the point of throw (top of the building). Represent the initial velocity and the acceleration vectors in the reference y-axis above. Find the maximum height the ball reaches with respect to the ground. How long does it take the ball to reach the...
