Question: If a 10 kg object experiences an impulse of 30 Ns, what is the change in its velocity?
Options:
3 m/s
2 m/s
1 m/s
4 m/s
Correct Answer: 3 m/s
Solution:
Impulse (J) = mass (m) × change in velocity (Δv) => Δv = J/m = 30 Ns / 10 kg = 3 m/s.

Questions & Step-by-Step Solutions
If a 10 kg object experiences an impulse of 30 Ns, what is the change in its velocity?
Step 1: Understand the problem. We have a 10 kg object and an impulse of 30 Ns acting on it.
Step 2: Recall the formula for impulse: Impulse (J) = mass (m) × change in velocity (Δv).
Step 3: Rearrange the formula to find the change in velocity: Δv = J / m.
Step 4: Substitute the values into the formula: Δv = 30 Ns / 10 kg.
Step 5: Calculate the change in velocity: Δv = 3 m/s.
Impulse and Momentum – Impulse is the product of force and the time duration over which it acts, and it results in a change in momentum, which can be expressed as the product of mass and change in velocity.
Basic Algebra – The question requires basic algebra to rearrange the formula for impulse to solve for change in velocity.
