Question: A 1000 kg car is moving at a speed of 20 m/s. What is its momentum? (2000)

Options:

  1. 2000 kg m/s
  2. 10000 kg m/s
  3. 5000 kg m/s
  4. 4000 kg m/s

Correct Answer: 10000 kg m/s

Exam Year: 2000

Solution: 

Momentum (p) is calculated using the formula p = m * v. Here, p = 1000 kg * 20 m/s = 20000 kg m/s.

Questions & Step-by-Step Solutions

A 1000 kg car is moving at a speed of 20 m/s. What is its momentum? (2000)
  • Step 1: Identify the mass of the car. The mass (m) is given as 1000 kg.
  • Step 2: Identify the speed of the car. The speed (v) is given as 20 m/s.
  • Step 3: Use the formula for momentum, which is p = m * v.
  • Step 4: Substitute the values into the formula: p = 1000 kg * 20 m/s.
  • Step 5: Calculate the momentum: p = 20000 kg m/s.
  • Momentum – Momentum is the product of an object's mass and its velocity, represented by the formula p = m * v.
