A man is pulling a 120 lb wooden box by a rope with a force of80 lb along a wooden floor. The rope is 45 degrees from thehorizontal. The coefficient of of dynamic friction between wood towood surfaces is Uk=0.45. If the box initially starts from rest,what will the box's (a) acceleration,and (b) velocity after 8 sec?(c) max power and (d) average power. Make sure to have FDB andkinetic diagrams, and unit base vectors.
