If the units of your answer are kg ∙ m2/s3, which of the following types of quantities could your answer be?

A. kinetic energy

B. potential energy

C. force

D. power

E. work

D. Power

Explanation:

Power is defined as "time rate of change in energy". So,

P = W/t

P = (kgm^2/s^2) / s

P = kgm^2/s^3

Now,

Units of potential Energy = units of kinetic energy = units of work = Fd = kgm^2/s^2

Units of force = F = ma = kgm/s^2

Hence, (D) Power is the right answer.

D. power

Explanation:

kg represents mass

(m/v) ² represents velocity squared

Then kg·m²/s² represents mass·velocity² = kinetic energy or potential energy or work.

kg·m²/s³ will be the rate of doing work, which is power
