Projectile Motion basketball shot

[kara1434]

eek.
I need help.

A basketball player shoots a basketball into a hoop to score a "point". The height of the hoop is 3m. The shooter stands 15 m from the basket and shoots the ball at a 55 degree andle from the horizontal. Assume the height of player is 0.

Need to find:
1) The baslketball's initial resultant velocity.
2) The maximum height of the basketball.

I think you need to use trigonometry and rearrange the equation for the horizontal component (because you have been given it) to get the inital resultant velocity (u).
hope that gives you a start
