Serena Willliams hits a ball 2.15 m above the ground. The ball leaves her racquet with a speed of 18 m/s at an angle of 8° above the horizontal. The horizontal distance to the net is 7.0 m and the net is 1.0 m high. Assuming that the local acceleration due to gravity is 9.80 m/s2, determine the distance (in m) between the ball and the top of the net at the moment the ball reaches the net (positive - the ball is above the net and negative - the ball is below the net).

Given:-
The height from the ball hit is h = 2.15 m above the ground
The initial speed of the ball is u = 18 m/s
The angle of the hit on the ball is 8° above the horizontal.
The horizontal distance to the net is x = 7.0 m
the height of net from the ground is y = 1 m
Find:-
Determine the distance (in m) between the ball and the top of the net at the moment the ball reaches the net?
