A 3.5 kg block, initially in motion, is pushed along a horizontal floor by a force F of magnitude 17 N at an angle θ = 35° with the horizontal (Figure 6-20). The coefficient of kinetic friction between the block and floor is 0.25. (Assume the positive direction is to the right.)

Figure 6-20

(a) Calculate the magnitude of the frictional force on the block from the floor.

N

(b) Calculate the magnitude of the block's acceleration.

m/s2
