Question: A 2 kg object is moving with a velocity of 4 m/s. What is its momentum? (2020)

Options:

  1. 8 kg m/s
  2. 4 kg m/s
  3. 2 kg m/s
  4. 16 kg m/s

Correct Answer: 8 kg m/s

Exam Year: 2020

Solution: 

Momentum (p) = m * v = 2 kg * 4 m/s = 8 kg m/s

Questions & Step-by-Step Solutions

A 2 kg object is moving with a velocity of 4 m/s. What is its momentum? (2020)
  • Step 1: Identify the mass of the object. In this case, the mass (m) is 2 kg.
  • Step 2: Identify the velocity of the object. Here, the velocity (v) is 4 m/s.
  • Step 3: Use the formula for momentum, which is p = m * v.
  • Step 4: Substitute the values into the formula: p = 2 kg * 4 m/s.
  • Step 5: Calculate the result: 2 kg * 4 m/s = 8 kg m/s.
  • Step 6: Conclude that the momentum of the object is 8 kg m/s.
  • Momentum – Momentum is the product of an object's mass and its velocity, represented by the formula p = m * v.
