Question #a5687

Answer 1

`W=2.4J`

Explanation:

The work done is the amount of energy transferred by a force. It is dependent on the force and distance that the force travelled. Therefore, work done = force x distance.
`W=fxxs`, but the distance`(s)` has to be in meters.
`40cm=0.4m` because,

`1cm=0.01m`
`40cm xx 0.01m=0.4m`

`W=6N xx 0.4m`

`=2.4J`

Answer 2

See the answer below...

Explanation:

We know that work done is equal to the dot product of the force and the distance covered... which we can mathematically represent as
>`W=F.S`

Here `F=6N` and `S=40/100m=0.4m`

Hence the work done is `6xx0.4` joule=`2.4` joule
