Answer:
[tex]\boxed {\boxed {\sf 157.5 \ Joules }}[/tex]
Explanation:
Work is equal to the product of force and distance.
[tex]W=F*d[/tex]
The box is being pushed with an effort (force) of 45 Newtons and the distance is 3.5 meters.
[tex]F= 45 \ N \\d= 3.5 \ m[/tex]
Substitute the values into the formula.
[tex]W= 45 \ N * 3.5 \ m[/tex]
Multiply.
[tex]W= 157.5 \ N*m[/tex]
- 1 Newton meter is equal to 1 Joule
- Our answer of 157.5 N*m equals 157.5 J
[tex]W= 157.5 \ J[/tex]
157.5 Joules of work are done on the crate.
