Respuesta :

Answer:

C. 574.53

Step-by-step explanation:

Option C) is correct work done = 574.53.

Force = 15 pounds
distance = 50 feet
Ф = 40°

What is work done?

work done is product of force and cosine of displacement.

work done = force x displacement x cosФ
= 15 x 50 x cos40
= 15 x 50 x 0.76
= 574.53

Thus the required work done is 574.53 to pull the wagon.
