Final answer:
Momentum, work, power, and kinetic energy all have units of kg·m²/s².
Step-by-step explanation:
The units of kinetic energy are mass times the square of speed, or kg·m²/s². But the units of force are mass times acceleration, kg·m/s², so the units of kinetic energy are also the units of force times distance, which are the units of work, or joules. Therefore, both kinetic energy and work have units of kg·m²/s².
So, the options that will have units of kg·m²/s² are:
- a) Momentum
- b) Work
- c) Power
- d) Kinetic energy
