10 ft-lbs.

40 ft-lbs.

0.5 ft-lbs.

Answer 1

The first one 10 ft-lbs I think

Answer 2

Answer:

It's 10 ft-lbs

Explanation:

In that case work done is not associated with time.

We will consider only Force aplied and the distance covered in the direction of force.

Therefore, Work done = Force × distance

= 2 lbs × 5 ft

= 10 ft-lbs

But in most cases answers are written in SI units.
