Projectile motion with a few variables

[mwks]

Homework Statement

Assume uniform acceleration. The projectile is released at a height 1m above the ground traveling at angle 60 above the horizontal. It hits the ground 60m away from the launch position. Calculate acceleration of the particle in acceleration phase.[/B]

Homework Equations

s=ut+1/2ut^2 in y direction
s=ut in x direction[/B]

The Attempt at a Solution

tried using the above two and substituting for time and initial velocity but both give horrible equations which i can't solve.
Tried the range formula but that doesn't work because of the 2m start position.[/B]

The simple equal height for launch and landing range formula is out, so you need to fall back on the basic projectile motion equations. Fortunately the angle provided has well known values for sine and cosine, so writing the projectile motion equations in terms of an unknown velocity v is made a bit easier.

Why don't you show us your attempt using the projectile motion equations and point out where you get stuck?

Got it now. I was just being silly thank you for your help :)
