Question

A 10 n force is applied horizontally on a box to move it 10 m across a frictionless surface. How much work was done to move the box?

Answer 1

Given from question
Force = 10 N
Displacement = 10 m
Work done = ?
We know that
Work done = force X displacement
So 10 X 10
100
Work done = 100J answer

Answer 2

`\boxed {\boxed {\sf 100 \ J}}`

Step-by-step explanation:

We are asked to calculate the work done to move a box.

Work is the product of force and distance or displacement.

`W= F*d`

A 10 Newton force is applied horizontally on the box. Since the surface is frictionless, there is no force of friction, and the net force is 10 Newtons. The force moves the box 10 meters.

• F= 10 N
• d= 10 m

Substitute the values into the formula.

`W= 10 \ N * 10 \ m`

Multiply.

`W= 100 \ N*m`

Let's convert the units. 1 Newton meter is equal to 1 Joule, therefore our answer of 100 Newton meters is equal to 100 Joules.

`W= 100 \ J`

100 Joules of work was done to move the box.
