Question

A weight lifter raises a 1600 N barbell to a height of 2.0 meters. How much work was done? W = Fd

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

Answer 1

the answer is D ithink because you have to times :

1600*2.0=3200 joules

Answer 2

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

Solution : Given,

Force applied = 1600 N

Displacement = 2 m

Formula used :

$W=F\times d$

where,

W = work done

F = applied force

d = displacement

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

$W=F\times d=(1600N)\times (2m)=3200J$

Therefore, the amount of work done was, 3200 Joules
