Assume that it is moving upside of the inclined plane having an angle thetha.
and then after just balance the forces in inclined direction.
Therefore,
Net force
mgsinthetha - umgsinthetha = ma..........(1)
at let it travels x distance,
then apply newton’s 2nd law of eqn.,
x = 0 + 0.5(gsinthetha - ugsinthetha)t^2.
