Question: A car of mass 1000 kg comes to a stop from a speed of 20 m/s. What is the impulse experienced by the car?

Options:

  1. 20000 Ns
  2. 10000 Ns
  3. 5000 Ns
  4. 40000 Ns

Correct Answer: 20000 Ns

Solution: 

Impulse (J) = change in momentum = mass (m) × change in velocity (Δv) = 1000 kg × (0 - 20 m/s) = -20000 Ns.

A car of mass 1000 kg comes to a stop from a speed of 20 m/s. What is the impulse experienced by the car?
  • Impulse and Momentum – Impulse is defined as the change in momentum of an object, which can be calculated as the product of mass and change in velocity.
  • Mass and Velocity – Understanding the relationship between mass, velocity, and how they contribute to momentum is crucial for solving impulse problems.
