Question

Calculate the work done by an applied force of 71.5 N on a crate for the following. (Include the sign of the value in your answer.) (a) The force is exerted horizontally while pushing the crate 4.30 m.

Answer 1

Answer:

W = 307.45 joules

Explanation:

the work done is defined as the product of force applied in the direction of displacement and the displacement.

Use the formula for work directly

(work) = (force) x (displacement)

Work is a scalar quantity and its SI unit is Joule.

W = F x d

F = 71.5 N

d = 4.30 m

W = 71.5 × 4.30

W = 307.45 joules
