Initially a small block of wood is at a point O on a rough plane inclined at 15* to the horizontal.
The block is projected directly up the plane with initial speed 4m/s.
The coefficient of friction between the block and the plane is 1/10.
The block comes instantaneously at rest at A.
i) Find the distance OA
ii) Find the speed of the block as it passed through O when moving back down the plane.
I would really appreciate it if someone could help me with this question as I've spent around half an hour trying to figure it out.
Many thanks.
