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

Step-by-step explanation:

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

Answer 2

Answer:

$\boxed {\boxed {\sf 45 \ Joules}}$

Step-by-step 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.
