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

D) 3200 joules is the answer

Answer 2

Answer : Work done, W = 3200 Joules.

Explanation :

The force acting on the berbell, $F=1600\ N$

The height attained by it, $h=2\ m$

We know that the relation between the work done, force acting and the displacement is given by :

$W=F\times d$

$W=1600\ N\times 2\ m$

$W=3200\ Joules$

The work done will be 3200 Joules.

So, the correct option is (D).

Hence, this is the required solution.
