A 10 kg object is moving with a speed of 2 m/s. What is its momentum?
Correct Answer: 20 kg·m/s
- Step 1: Identify the mass of the object. In this case, the mass is 10 kg.
- Step 2: Identify the speed (velocity) of the object. Here, the speed is 2 m/s.
- Step 3: Use the formula for momentum, which is Momentum (p) = mass × velocity.
- Step 4: Substitute the values into the formula: p = 10 kg × 2 m/s.
- Step 5: Calculate the result: 10 kg × 2 m/s = 20 kg·m/s.
- Step 6: The momentum of the object is 20 kg·m/s.
- Momentum – Momentum is the product of an object's mass and its velocity, representing the quantity of motion an object has.
