Question

Ned the skydiver weighs 600 N and is falling at terminal speed. That is, he has sped up until air resistance has built up so much that he has reached a final constant speed. How much work does Ned do on the air as he falls through 200 m at this terminal speed?

Answer 1

The work done is 120000 J.

Step-by-step explanation:

Given that,

Weight = 600 N

Distance = 200 m

We need to calculate the work done

Using formula of work done

`W=F* d`

Where, F = force

d = distance

Put the value into the formula

`W=600*200`

`W=120000\ J`

Hence, The work done is 120000 J.
