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
