Questions & Step-by-Step Solutions

A 12 kg object is moving with a velocity of 3 m/s. What is its momentum? (2019)
  • Step 1: Identify the mass of the object. The mass is given as 12 kg.
  • Step 2: Identify the velocity of the object. The velocity is given as 3 m/s.
  • Step 3: Use the formula for momentum, which is p = mv, where p is momentum, m is mass, and v is velocity.
  • Step 4: Substitute the values into the formula: p = 12 kg * 3 m/s.
  • Step 5: Calculate the momentum: 12 kg * 3 m/s = 36 kg·m/s.
  • Momentum – Momentum is the product of an object's mass and its velocity, represented by the formula p = mv.
