Aweight 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 : Work done, W = 3200 Joules.

Explanation :

The force acting on the berbell,

The height attained by it,

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

The work done will be 3200 Joules.

So, the correct option is (D).

Hence, this is the required solution.

the results is a decrease in air temperature with an increase of altitude.
