A long jumper rises 0.5 meters during the flight phase of his jump. His forward velocity is 8 ms. What is the upward velocity?

2. Relevant equations

3. The attempt at a solution

Vv=Vsin[itex]\vartheta[/itex]

So [itex]\vartheta[/itex] is the unkown

Okay, I did a skectch to work out basic trig, with 8m/s as my H and 0.5m as my 0

using sin[itex]\vartheta[/itex]=o/h, =0.5/8 = 3

Then VV=8Sin3 = 0.38 m/s (which is wrong, but where did I go wrong??
