Question: A 5 kg object is moving at a velocity of 3 m/s. What is its momentum?

Options:

  1. 15 kg·m/s
  2. 5 kg·m/s
  3. 3 kg·m/s
  4. 10 kg·m/s

Correct Answer: 15 kg·m/s

Solution: 

Momentum (p) = mass (m) × velocity (v) = 5 kg × 3 m/s = 15 kg·m/s.

  1. 15 kg·m/s
  2. 5 kg·m/s
  3. 3 kg·m/s
  4. 10 kg·m/s

Questions & Step-by-Step Solutions

A 5 kg object is moving at a velocity of 3 m/s. What is its momentum?
  • Step 1: Identify the mass of the object. In this case, the mass (m) is 5 kg.
  • Step 2: Identify the velocity of the object. Here, the velocity (v) is 3 m/s.
  • Step 3: Use the formula for momentum, which is Momentum (p) = mass (m) × velocity (v).
  • Step 4: Substitute the values into the formula: p = 5 kg × 3 m/s.
  • Step 5: Calculate the result: 5 kg × 3 m/s = 15 kg·m/s.
  • Step 6: Conclude that the momentum of the object is 15 kg·m/s.
  • Momentum – Momentum is the product of an object's mass and its velocity, representing the quantity of motion an object has.
