How much work will it take to lift a 2-kg pair of hiking boots 2 meters off the

ground and onto a shelf in your closet?

O A. 2.45 J

OB. 4J

C. 39.2 J

D. 20 J

Option C - 39.2 J

Explanation:

We are given that;

Mass; m = 2 kg.

Distance moved off the floor; d = 10 m.

Acceleration due to gravity; g = 9.8 m/s².

We want to find the work done.

Now, the Formula for work done is given by;

Work = Force * displacement.

In this case, it's force of gravity to lift up the boots, thus;

Formula for this force is;

Force = mass x acceleration due to gravity

Force = 2 * 9.8 = 19.2 N

∴ Work done = 19.6 * 2

Work done = 39.2 J.

Hence, the Work done to life the boot of 2 kg to a height of 2 m is 39.2 J.
