A ball is kicked with an initial velocity of 15.5 m/s in the horizontal direction and 10.5 m/s in the vertical direction.
vx = 15.5 m/s
vy = 10.5 m/s
Part (a) At what speed does the ball hit the ground in m/s?
Part (b) For how long does the ball remain in the air in seconds?
Part (c) What maximum height is attained by the ball in meters?
