Question

A box is pulled with a force of 25 N to produce a displacement of 15 m. If the

angle between the force and displacement is 30°, find the work done by the force.

Answer 1

324.76J

Step-by-step explanation:

Given parameters:

Force of pull on the box = 25N

Displacement = 15m

Angle of pull = 30°

Unknown:

Work done by the force = ?

Solution:

Work done is the force applied on a body to move it through a particular distance.

It can be expressed as;

Work done = F x dcosФ

F is the force

d is the displacement

Ф is the angle

So;

Work done = 25 x 15cos 30 = 324.76J
