Question

Which object has a greater momentum? 1. A 2500 kg truck moving at 0.01 m/s. 2. A 0.1 kg bullet traveling at 300 m/s. 3. They are the same.

Answer 1

The momentum is greater for  0.1 kg bullet traveling at 300 m/s

Explanation:

Momentum = Mass x Velocity.

A 2500 kg truck moving at 0.01 m/s

      Momentum = Mass x Velocity

      Momentum = 2500 x 0.01 = 25 kgm/s

A 0.1 kg bullet traveling at 300 m/s

      Momentum = Mass x Velocity

      Momentum = 0.1 x 300 = 30kgm/s

Momentum of 0.1 kg bullet traveling at 300 m/s > Momentum of 2500 kg truck moving at 0.01 m/s.

The momentum is greater for  0.1 kg bullet traveling at 300 m/s
