Question: A car of mass 1000 kg is moving with a velocity of 20 m/s. What is the momentum of the car?

Options:

  1. 2000 kg·m/s
  2. 10000 kg·m/s
  3. 5000 kg·m/s
  4. 40000 kg·m/s

Correct Answer: 10000 kg·m/s

Solution: 

Momentum p = mv = 1000 kg * 20 m/s = 20000 kg·m/s.

Questions & Step-by-Step Solutions

A car of mass 1000 kg is moving with a velocity of 20 m/s. What is the momentum of the car?
  • Step 1: Identify the mass of the car. The mass is given as 1000 kg.
  • Step 2: Identify the velocity of the car. The velocity is given as 20 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 = 1000 kg * 20 m/s.
  • Step 5: Calculate the momentum: 1000 kg * 20 m/s = 20000 kg·m/s.
  • Momentum – Momentum is the product of an object's mass and its velocity, represented by the formula p = mv.
