Homework Statement
hi, i was trying to figure out how to tackle this physics question, but I am 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 angle 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 I am just stuck about where to start. thanks for helping me.
Homework Equations
i used v^2=u^2+2as and Vox=Vo*cos(angle) <- but i think I am wrong :S
The Attempt at a Solution
i got a=-28.57m/s. but and i got that it didn't claer the net. I am not sure wot i was doing really. :S
