A disk with mass m and radius R is rolling down a hill with no slipping, until it reaches a wall and then stops:

I want to write a set of equations describing the position cordinates x and y of the disk's center of mass (point A) and the cordinates for point B.

mgsin(theta)=ma -> gsin(theta)=a -> gsin(theta)=dv/dt ; V_B=2wR ; V_A=wR

Can you help me figure this out and guide me towards the solution?

Thanks,

Sharon
