A homework question that i need help with

[crazy_life]

hi, i was trying to figure out how to tackle this physics question, but im a little stuck. the question is:

a tennis player, playing for a match hits a ball 2m above the groung. the ball leaves his racquet with a speed of 20m/s at an angel of 5 above the horizontal. the horizontal distance to the net is 7m and the net heigh is 1m does the ball clear the net?

i've diagram to help me and im just stuck about where to start. thanks for helping me.

How long does it take the ball to reach the net, i.e., traverse the distance of 7m?

What is it's height at the time?
