A box is pulled with a rope at 26° to the horizontal and a tension of 120N. What is the work done in pulling it 5 metres?

Work done = Force in direction of motion (horizontal in this case) x distance. Force in direction of motion is 120 x cos(26) (draw a diagram to help visualise this) and distance is 5. Therefore work done is 120 x cos(26) x 5 = 539.276... = 539 J to 3.s.f
