I was Given 22 degree angle and the coefficient of friction (kinetic) is .22. Height of 9.10m (from rest at the top).

I calculated acceleration while it travels down the slop and got 1.6721.

I next need to calculate the speed when it reaches the bottom of the incline.

I thought i would simply need to use 2*G*H ^(1/2) . It gives me 13.355 and it is wrong.

Any help would be greatly appreciated or any equations i can use.

Thanks from a new user.

Paul.
