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

zalisa [80]

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 <u>45 Joules.</u>

nataly862011 [7]

Answer:

D

Step-by-step explanation:

If you ask questions while their speaking it shows that you are paying attention to them. Avoiding eye contact could mean your thinking about something else or you aren't interested. Interrupting them is just being disrespectful. Leaning towards them doesn't really do anything other than you moving.
