CONCEPT:

  • Momentum (p): The momentum of a body is the product of its mass and velocity.
    • It is a vector quantity.
    • The SI unit of momentum is kg.m/s.

Momentum (p) = Mass (m) × Velocity (v)

CALCULATION:

Given that:

mass (m) = 60 kg

Velocity (v) = 2 m/s

We know that:

Momentum = mass × velocity = 60 × 2 = 120 kg-m/s
