Ablock is released from rest at the top of a plane inclined at an angle of 21◦ . the coefficient of kinetic friction varies along the plane according to the relation µk = σx, where x is the distance along the plane measured in meters from the top and where σ = 0.7 m−1 . the acceleration of gravity is 9.8 m/s 2 .

determine how far the block slides before coming to rest. (hint: find the acceleration of the block and integrate to find the velocity. note that dv dt = dv dx dx dt answer in units of m
