## Homework Statement

Someone throws a ball 1m from the ground at a 30 degree angle to the corner of the room 8m away and elevated by 1m. Find the initial velocity of the ball.

## Homework Equations

s=ut+1/2at^2

## The Attempt at a Solution

So i broke it up into vector components in order to find the time for each component, ihave this so far...

Vertical

0=u(cos30)t+1/2*-9.8*t^2

Horizontal

8=u(sin30)+1/2*0*t^2

I dont really know where to go from here after i have rearranged to find the time of each component, i thought i could use simultaneous equations to find the inital velocity but i'm unsure of how i would go about it and my algebra isn't too good.

Please let me know what you would do after this or if there is some formula i may have missed out on that could help me solve this question.
