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

I am Lyosha [343]

Answer:

$\boxed {\boxed {\sf 157.5 \ Joules }}$

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

$W= 157.5 \ J$

<u>157.5 Joules </u> of work are done on the crate.
