Question

A mass of 10 kg is pulled up a slope at a steady speed by applying a force of 80N parallel to the slope as shown.Find the work done.​

Answer 1

Answer:

640 J

Explanation:

Force = mass × acceleration

80 = 10 × a

8 = a

acceleration = displacement / (time)^2

8 = d × (1)^2

8 = d × 1

8 = d

work = force × displacement

work = 80 × 8

work = 640 J
