A ball is launched with an initial velocity of 4 m/s off of a 100 meter tall building at an angle of 53 above the horizontal. What are the horizontal and vertical components of the ball's velocity at its maximum height? Assume no air resistance.
A. Horizontal = 0 m/s, Vertical = 3.2 m/s
B. Horizontal = 2.4 m/s, Vertical = 0 m/s
C. Horizontal = 2.4 m/s, Vertical = 3.2 m/s
D. Horizontal = 4 m/s, Vertical = 0 m/s
