This is from OCR Mechanics 1:
A block of wood of mass 4kg is released from rest on a plane inclined at 30 degrees to the horizontal. ASsuming that the surface can be modelled as smooth (no friction), calculate the acceleration of the block, and its speed after it has moved 3m.
I'm assuming I have to resolve it parallel to the ramp, but I don't know what to do! Can someone please help!!!!
