Question

A force of 157 N is applied to a box 25o above the horizontal. If it is applied over a distance of 14.5 m how much work is done?

Please show work

Answer 1

The answer to your question is: W = 2063.4 J

Step-by-step explanation:

Data

Force = 157 N

angle = 25°

distance = 14.5 m

W = ?

Process

- Find the horizontal force

cos Ф = adjacent side / hypotenuse

adjacent side = hypotenuse x cosФ

a.s. = 157 x cos 25

a. s. = 142.3 N

- Find the work

W = F x d

W = 142.3 x 14.5

W = 2063.4 J
