During service, a tennis ball is struck at height h = 1.5 m above a tennis court and moves with velocity v0 = v0xi. Assume the ball encounters no air resistance, and use a Cartesian coordinate system with the origin located at the ball’s initial position.
h = 1.5 m
v0x = 22.5 m/s
A) Calculate the tennis ball’s horizontal velocity, vfx in m/s, when it strikes the court.
B) How long, tf in seconds, does the tennis ball move before striking the court?
C) How far horizontally from the service position, xf in meters, does the tennis ball move before striking the court?
