What's the force due to gravity acting down a slope? What acceleration would this cause?

Thanks i got it now. W=sintheta so if i use F=ma i get sintheta = a/g. I havent come across an angle question like this before anyways thanks!!

a= g sin theta is for acceleration
its derived from a = gm (sin theta)/m gm is the weight, times sin theta, giving the force parallel to the slope acting on the rider.
all over the mass so its Force/mass = acceleration.
