The answer to your calculation has units of kg·m2/s, what type of quantity could it be? a. work. b. power. c. fore. d angular momentum. e. linear momentum.

D. angular momentum.

Explanation:

The angular momentum is defined as follows:

Where is angular momentum, is moment of inertia and is the angular velocity

Analyzing the units:

The units of are

The units of are

And when we miltiply them we get

So the anwer is angular momentum.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
