A baseball is hit at angle theta and is caught at the same height from which it was it. If the ball is hit at a 30 degee angle, with what speed must it leave the bat to travel 100m?

Question

*it should say hit

anonymous · Answer

at first, I was thinking tha i might need to use the range formula, bu since its not asking me for that, I'm assuming that I would need to first find the intial time to leave the bat

anonymous · Answer

So would i need to use the quadratic formula in this?

anonymous · Answer

use kinematic equation. Same height caught = imagine that the position of y = 0. 
It would be helpful to have 2 equations, 1 for the x direction, and one for the y direction. X has no acceleration, while y-component does.

Perhaps, you can use
$$x=\frac{vi^2}{g} \sin2\theta i$$

You should be able to get the value of Vi, the one that you are looking for.

okay i'll try that and see what i get.
