Anyone remember momentum? No? Me neither. Allow me to briefly check my notes.

Oh, right, now I remember. momentum= mass* velocity
What fun can we have with this? Well, I weigh... let's see... 43.54 kg, and a man I will refer to only as "my dad" (not his real name!) weighs 75.45 kg. If I take off running at 5 m/s (according to this comic, that's faster than a jog but slower than a sprint), my momentum will be 217.70 (kg*m)/s. My dad would only have to ambulate at 2.89 m/s (somewhere between walking and jogging) to attain the same momentum.
That's well and good, but... eh. Boring. What else could we do with this information? Oh, right.

We own a cat! After a good deal of squirming and piteous mewling (on his part, not mine), I have ascertained that his weight is about 5.90 kg (he is a chubby cat). For him to match our momentum, he'd have to run at 36.90 m/s. That's faster than the speed you drive at on an interstate! Nice. I may need to devise some sort of cannon.
