Questions & Step-by-Step Solutions

A 15 kg object is moving with a velocity of 4 m/s. What is its momentum? (2019)
Correct Answer: 60 kg m/s
  • Step 1: Identify the mass of the object. The mass is given as 15 kg.
  • Step 2: Identify the velocity of the object. The velocity is given as 4 m/s.
  • Step 3: Use the formula for momentum, which is Momentum = mass × velocity.
  • Step 4: Substitute the values into the formula: Momentum = 15 kg × 4 m/s.
  • Step 5: Calculate the result: 15 kg × 4 m/s = 60 kg m/s.
  • Momentum – Momentum is the product of an object's mass and its velocity, representing the quantity of motion an object has.
