📝 Velocity in Derivation

Q1. A particle moves with position function \(s = f(t) = 3t^2 + 2t\). What is the average velocity over \([1,3]\)?

💡 Difficulty: easy | ✅ Correct: C

Q2. For \(s = f(t) = t^3 - 3t\), find the instantaneous velocity at \(t_0 = 1\).

💡 Difficulty: medium | ✅ Correct: A

Q3. For \(s = f(t) = t^2 + \frac{1}{t}\), find the velocity at \(t_0 = 1\).

💡 Difficulty: hard | ✅ Correct: A
