A body builder exerts 15 N of force over 3 m. How much work did she do?
3.33 J


5 J


45 J


15 J


Sagot :

Work done = force x distance

work done = 15 x 3

work done = 45J

Answer:

[tex]\boxed {\boxed {\sf 45 \ Joules}}[/tex]

Explanation:

Work is the force the causes the movement or displacement of an object. It is the product of force and displacement.

[tex]W=Fd[/tex]

The force is 15 Newtons and the displacement is 3 meters.

  • F= 15 N
  • d= 3 m

Substitute the values into the formula.

[tex]W= 15 \ N * 3 \ m[/tex]

Multiply.

[tex]W= 45 \ N*m[/tex]

1 Newton meter is equal to 1 Joule, so our answer of 45 Newton meters is equal to 45 Joules.
