a block of mass = 3.0 kg slides along a floor while a force F of magnitude 12.0 N is applied to it at an upward angel ϴ. The coefficient of kinetic friction between the block and the floor is μ = 0. 40. (We can vary ϴ from 0 to 90, but block still remain on the floor). What vale of ϴ gives the maximum value of the lock’s acceleration magnitude “a” ? Calculate.
