A 5.0-kg object slides down a frictionless surface inclined at an angle of 30^o from the horizontal. The total distance moved by the object along the plane is 10 meters. The work done on the object by the normal force of the surface is: A) 0 kJ B) 0.50 kJ C) 0.43 kJ D) 0.58 kJ E) 0.25 kJ

Question

Quizplus · Accepted Answer

Since the surface is frictionless, the work done by the normal force is zero. Therefore, the answer is A) 0 kJ.
