A cart with mass $0.250kg$ is moving at a velocity of $0.400m/s$. What is its momentum?

• A. $0.650kg\cdot m/s$
• B. $0.150kg\cdot m/s$
• C. $0.100kg\cdot m/s$
• D. $0.025kg\cdot m/s$

Answer: (C)

Verified step by step guidance

1. Identify the given quantities: mass of the cart \(m = 0.250\ \text{kg}\) and velocity \(v = 0.400\ \text{m/s}\).
2. Recall the formula for momentum, which is the product of mass and velocity: \(p = m \times v\).
3. Substitute the given values into the momentum formula: \(p = 0.250 \times 0.400\).
4. Multiply the numbers to find the momentum value (do not calculate the final number here, just set up the expression).
5. Express the momentum with the correct units: \(\text{kg} \cdot \text{m/s}\).
