What is the velocity needed for a trampoline jump?

[haengbon]

Homework Statement

A man jumps on a trampoline with an angle of 53$$\circ$$ with respect to the horizontal. What velocity does he need in order to be caught by the other man who is 5.2 m away from him, and 6.1 m above the ground?

Homework Equations

so I guess...

X= 5.2 m
Y= -6.1 m

am I correct?

The Attempt at a Solution

So far, the only thing I've actually understood is..

Vix = Vxcos30$$\circ$$
Viy = Vysin30$$\circ$$

Can someone please guide me through this?

What do you know about projectile motion ? Why do you use 30° angle? What is Vx, Vy?
