A 3.02 kg block is pushed along a horizontal floor by a force F→ of magnitude 34.0 N at a downward angle θ = 40.0∘. The coefficient of kinetic friction between the block and the floor is 0.240 . Calculate the magnitudes of (a) the frictional force on the block from the floor and (b) the block's acceleration. (a) Number Units N (b) Number Units m/s^2
