Question

A large crate is pushed across the floor with an effort of 45 Newtons. The box is pushed a distance of 3.5 meters. How much work is done?

Answer 1

`\boxed {\boxed {\sf 157.5 \ Joules }}`

Step-by-step explanation:

Work is equal to the product of force and distance.

`W=F*d`

The box is being pushed with an effort (force) of 45 Newtons and the distance is 3.5 meters.

`F= 45 \ N \\d= 3.5 \ m`

Substitute the values into the formula.

`W= 45 \ N * 3.5 \ m`

Multiply.

`W= 157.5 \ N*m`

• 1 Newton meter is equal to 1 Joule
• Our answer of 157.5 N*m equals 157.5 J

`W= 157.5 \ J`

157.5 Joules of work are done on the crate.
