Question

conpare the momenta of a 6300 elphant walking 0.11 ms and a 50kg dolphing swimming 10.4m ms

Answer 1

I'll assume the masses and speeds are in kg and m/s. Momentum p = m·v.

- Elephant: m = 6300 kg, v = 0.11 m/s
p_elephant = 6300 × 0.11 = 693 kg·m/s

- Dolphin: m = 50 kg, v = 10.4 m/s
p_dolphin = 50 × 10.4 = 520 kg·m/s

Comparison: 693 vs 520 kg·m/s — the elephant has the larger momentum.
Ratio p_elephant / p_dolphin ≈ 693 / 520 ≈ 1.33, so the elephant's momentum is about 1.33 times (≈33%) greater than the dolphin's.

(If directions differ, momentum is a vector; these numbers are magnitudes.)
