Question

The amount of work done by two boys who apply 310 N of force in an unsuccessful attempt to move a stalled car is

1. 310 N · m.
2. 620 N.
3. 310 N.
4. 0.5.620 N · m

Answer 1

Answer:0 N-m

Explanation:

Given

Force applied is given by $F=310 N$

It is given that there is no movement of car

therefore Net displacement is zero i.e. $s=0$

Work done is given by

$W=F\cdot s$

$W=310\cdot s$

$W=310\cdot 0$

$W=0\ N-m$
