Answer:

168 J

Explanation:

Work can be calculated using the following formula.

w=f*d

where w is work, f is force, and d is distance.

Anna applied a force of 84 Newtons, and lifted the baby 2.0 meters.

f=84 N

d=2 m

Substitute these variables into the formula.

w=84 N* 2 m

Multiply

w=168 N-m

A N-m is the same as a Joule, or J.

w= 168 Joules

Anna does 168 Joules of work.
