roadjester · Answer

would have less what?

anonymous · Answer

less momentum than a 52 kg cheetah

roadjester · Answer

Momentum $\vec p$ is defined as mass*velocity (m$\vec  v$).
So just multiply.

anonymous · Answer

Would be D

momentum is kg* m/s
Cheetah is 52 kg * 10 m/s = 520 kgm/s
Zebra is 61kg * 8 m/s = 488 kgm/s
