Homework Statement
An Olympic long jumper is capable of jumping 7.7m. Assuming his horizontal speed is 8.8m/s as he leaves the ground, how long is he in the air? Assume that he lands standing upright--that is, the same way he left the ground.
Homework Equations
Y = xtan(theta)0 - ((g)/2V02cos2(theta)0)X2
Vx0 = V0cos(theta)t
And other that I attempted at using...
The Attempt at a Solution
Ok so I have tried several things but, I don't have the angle at which he jumps to figure out the time, and you only get the initial velocity for the horizontal direction. I was going to use
Vx0 = V0cos(theta)t
to solve for Cos(theta) and figure out my angle but I don't even Have V, only Vx so am I suposed to assume they are the same?
If someone can point me in the right direction, this is the only problem I couldn't figure out earlier today.
