Question

A boy pulls a rope attached to a 22 kg sled on an icy, frictionless surface with an acceleration of 2.0 m/s². Calculate the work done by the boy if he is pulling the rope at 35° to the horizontal and for 15 m?

Answer 1

Ok so the wording on this question is odd as it does not specify what direction the acceleration is in assuming it is horizontal W = Fd (if force is constant) and F = ma so W=mad = 22*2*15 = 660J

Answer 2

22*2*15=660 Joules
