A 2.00-kg block starts from rest at the top of a 30.0∘ incline and slides a distance of 2.10 m down the incline in 2.00 s. (a) Find the magnitude of the acceleration of the block. m/s2 (b) Find the coefficient of kinetic friction between block and plane. (c) Find the friction force acting on the block. magnitude N direction (d) Find the speed of the block after it has slid 2.10 m. m/s
