A block of mass m is projected at speed Vo up a rough plane inclined at an angle theta to the horizontal. Model the block as a particle and assume that the frictional force acting is given by kv^2, where v is the block's speed and k is a constant.

What is the block's equation of motion, where after time t, the block has moved a distance x up the slope and has speed V>0?

Please help! Many thanks!!
