[Ans: 120
a.​

Answer 1

`\boxed {\boxed {\sf 120 \ Joules}}`

Step-by-step explanation:

Work is equal to the product of force and distance.

`W=F*d`

The force is 8 Newtons and the distance is 15 meters.

`F= 8 \ N \\d= 15 \ m`

Substitute the values into the formula.

`W= 8 \ N * 15 \ m`

Multiply.

`W= 120 \ N*m`

• 1 Newton meter is equal to 1 Joule
• Our answer of 120 N*m equals 120 J

`W= 120 \ J`

The work done is 120 Joules
