Question

How much work does a person do in pushing a box with a force of $20N$ over a distance of $8.0m$ in the direction of the force?

• A. $1.6J$
• B. $16J$
• C. $160J$
• D. $1600J$
• E. $16000J$

Answer 1

The correct option is C $160J$

Given,

Force applied, $F=20N$

Displacement, $d=+8.0m$ (in the direction of the force)

Work done, $W$

$W=F\times d$

$W=20\times 8$

$W=160J$
