A 3.50 kg block is pushed along a horizontal floor by a force of magnitude 15.0 N at an angle 0 = 30.0° with the horizontal (see the igure below). The coefficient of kinetic friction between the block and the floor is 0.250. Calculate the magnitudes of (a) the frictional Force on the block from the floor and (b) the block's acceleration.
