A) 30 Joules
B) 3000 Joules
C) 320 Joules
D) 3200 Joules

Respuesta :

the answer is D ithink because you have to times :

1600*2.0=3200 joules

Answer : The correct option is, (D) 3200 Joules

Solution : Given,

Force applied = 1600 N

Displacement = 2 m

Formula used :

[tex]W=F\times d[/tex]

where,

W = work done

F = applied force

d = displacement

Now put all the given values in the above formula, we get the work done.

[tex]W=F\times d=(1600N)\times (2m)=3200J[/tex]

Therefore, the amount of work done was, 3200 Joules
