Question

Calculate work when the force exerted to push an object is 75 n and the distance is 1.2 kilometers.

Answer 1

The magnitude of the work done to push the object is 90,000 J

When is Work done on a body ?

Work is done on a body when the direction of the force applied is parallel to the direction of the displacement of the body.

The following parameters are given;

• Force F = 75 N

• Distance S = 1.2 Km

• Work W = ?

First convert the distance in kilometer to meter by multiplying it by 1000

S = 1.2 x 1000 = 1200 m

From the definition of work,

W = F x S

Substitute the parameters into the formula

W = 75 x 1200

W = 90,000 J

Therefore, the magnitude of the work done to push the object is 90,000 J
