Question

which has more momentum a) a bullet of mass 0.02 kg moving at 400m/s. b) a car of mass 3000 kg moving at
5m/s.
​

Answer 1

Answer:

The Car

Explanation:

a) m = 0.02 kg

v = 400 m/s

⇒ p = mv = (0.02)(400) = 8 kgm/s

b) m = 3000 kg

v = 5 m/s

⇒ p = mv = (3000)(5) = 15,000 kgm/s

Hence the car has more momentum.
