Question

in physics, work is defined as ( f cdot d ) where ( f ) is the force applied over a distance of ( d ). a box is dragged across 20 meters with a force of 60 newtons, which are ( \frac{\text{kg} cdot \text{m}}{\text{s}^2} ). what calculation will give us the work done, in joules (which are ( \frac{\text{kg} cdot \text{m}^2}{\text{s}^2} ))? choose 1 answer:
a ( 20 cdot 60 )
b ( 20 cdot 1000 cdot 60 )
c ( \frac{20}{1000} cdot 60 )
d ( \frac{20}{60} )

Explanation:

Step1: Recall the work formula

Work \( W = F \cdot D \), where \( F = 60 \) Newtons and \( D = 20 \) meters.

Step2: Substitute values into the formula

Substitute \( F = 60 \) and \( D = 20 \) into \( W = F \cdot D \), we get \( W = 20 \cdot 60 \).

Answer:

A. \( 20 \cdot 60 \)
