QI) A 5 kg block initially at rest is pulled to the right along a horizontal surface by a constant horizontal force of 12 N. (A) Find the speed of the block after it has moved 4 m if the surfaces in contact have a coefficient of kinetic friction of 0.15 as shown in Figure (a). (B) Suppose the force F is applied at an angle 0 as shown in Figure (b). At what angle should the force be applied to achieve the largest possible kinetic energy?
