You are pulling a child in a wagon. The rope handle is inclined upward at a 60o angle. The tension in the handle is 20 N. How much work do you do if you pull the wagon 100 m at a constant speed?

Respuesta :

Answer:

1000 J

Explanation:

Tension force, F = 20 N

distance, d = 100 m

angle, θ = 60°

Work done = force x distance x Cos θ

W = 20 x 100 x Cos 60

W = 2000 x 0.5

W = 1000 J

thus, the work done is 1000 J.
