Question

Which of the following has the greatest momentum?

a) turtle with a mass of 100 kg moving at a velocity of 1.0 m/s

b) tortoise with a mass of 300 kg moving at a velocity of 0.5 m/s

c) roadrunner with a mass of 2 kg moving at a velocity of 7 m/s

d) hare with a mass of 200 kg moving at a velocity of 7 m/s

Answer 1

Step-by-step explanation:

a)

p₁ = m₁·V₁ = 100·1.0 = 100 kg·m/s

b)

p₂ = m₂·V₂ = 300·0.5 = 150 kg·m/s

c)

p₃ = m₃·V₃ = 2·7 = 14 kg·m/s

d)

p₄ = m₄·V₄ = 200·7 = 1400 kg·m/s

The greatest momentum:

d) hare with a mass of 200 kg moving at a velocity of 7 m/s

p = 1400 kg·m/s

Answer 2

I believe the hare (option d)

Step-by-step explanation:

Momentum is an objects mass multiplied by its velocity
