This is the question:

An athlete executing a long jump leaves the ground at a 35° angle and travels 5.80 m.

a) What was the takeoff speed?

b) If this speed were increased by just 5.0 percent, how much longer would the jump be?

ive worked out the initial velocity = speed x sin 35 (is that rite)

i know it has somethin to do with the angle and sin but im not sure how to put it onto an equation :S i keep getting 3.32 but its not rite :(

wat am i doin wrong?
