Question

A 2.0 kilogram mass is pushed along a horizontal surface by a 3.0 N force. How much work is done in moving the object 1.5 meters?

Answer 1

`4.5J`

Explanation:

Work done `=`force`xx`distance

in this case we have

`F=3N`

`d=1.5m`

the mass is irrelevant for this calculation

`WD=3xx1.5=4.5J`
