Finding final kinetic energy and final velocity?

A solid ball of mass 15 kg is at the top of a frictionless incline 2 m high and 10 m long. If it rolls down the incline, find its:

(a) initial potential energy
(b) final kinetic energy
(c) final velocity.

So far, I've done (a), hopefully it's right.

I did ...

GPE = mgh, so 15 x 9.8 x 2 = 294 J.

I'm stuck with the next part, (b).

The formule is KE = mv2 (squared) divided by 2.

I've got the mass but the thing is I don't have the velocity to work out the kinetic energy.

To work out the velocity you generally need the kinetic energy.

I'm confused.

If anyone could help out that'd be great.

This is tenth grade physics by the way =)

I have a question about vectors if anyone has an idea.?

I have started learning about vectors for A level and cant really remember anything about GCSE math.

I have to find an angle of 2 vectors. I have done the equation and am left with -1 / 6. The example says the answer is 99.6 and I am trying to figure out why?
