Question

Shawn uses 45N of force to stop the cart 1 meter from running his foot over. How much work does he do?​

Answer 1

Explanation:

`\sf Required\:Answer\begin{cases} \sf Force_(f)=45N \\ \sf Distance_(d)=1m \\ \sf As\:we\:know\:that \\ {\boxed{\sf Work_(w)=Force_(f)* Distance_(d)}} \\ \sf W=45 * 1Nm \\ \sf =45Nm \\ \longrightarrow {\underline{\boxed{\bf W=45Joule}}}\end {array}`

Answer 2

`\boxed {\boxed {\sf 45 \ Joules}}`

Explanation:

Work can be found by multiplying the force by the distance traveled in the direction of the force.

`W=F*d`

The force is 45 Newtons.

The distance traveled is 1 meter.

`F=45 \ N \\d= 1 \ m`

Substitute the values into the formula.

`W=45 \ N * 1 \ m`

Multiply.

`W=45 \ N*m`

1 Newton meter is equal to 1 Joules.

Therefore our answer of 45 Newton meters is equal to 45 Joules.

`W= 45 \ J`

The work done is 45 Joules.
