No I don't, I use the x component in equation 1 and get the time then I plug the time back into equation 2 along with the y component and solve correct?
Distance between tennis ball and the top of the net
Click For Summary
SUMMARY
The discussion focuses on calculating the distance between a tennis ball and the top of the net during a serve. The player serves the ball at a speed of 25.3 m/s from a height of 2.5 m, with the net positioned 12 m away and 0.9 m high. The calculations involve using kinematic equations to determine the time of flight and the vertical position of the ball at the net. The final results indicate that when served horizontally, the ball is 0.66 m above the net, while serving at a 5° downward angle results in the ball being 1.54 m above the net.
