# Physics help!!! watch

1. A tennis player serves a ball from a height of 2.51 m at 18.0 ms–1 in a horizontal direction. The ball just clears the net which is 1.00 m high. In this question assume that air resistance is negligible.
(a) Show that the ball takes approximately 0.6 s to reach the net after being served.

(b) (i) Calculate the vertical component of the velocity of the ball as it passes over the net.

Ive done A but no idea how you do b?? can someone help???
2. Well you know how long it has been travelling before it reaches the net, use a suvat equation vertically to find the final velocity (under acceleration of free fall). Initial velocity would be 0, as vertical/horizontal components are separate and apart from horizontal motion it has essentially been dropped if you only think of vertical motion.
