Explanation:
The given figure shows four balls A,B,C and D. Momentum of an object is defined as the product of its mass and velocity.
Momentum of ball A, p₁ = m₁v₁ = 0.7 kg × 15 m/s = 10.5 kg-m/s
Momentum of ball B, p₂ = m₂v₂ = 5.5 kg × 1.2 m/s = 6.6 kg-m/s
Momentum of ball C, p₃ = m₃v₃ = 5 kg × 2.5 m/s = 12.5 kg-m/s
Momentum of ball D, p₄ = m₄v₄ = 1.5 kg × 5 m/s = 7.5 kg-m/s
So, ball C has the greatest amount of momentum and ball B has the least amount of momentum.
