📝 Velocity vs Time

Q1. A dragster's velocity varies linearly from 0 m/s at \(t = 0\) s to 30 m/s at \(t = 5\) s. What distance does it travel during this interval?

💡 Difficulty: easy | ✅ Correct: A

Q2. A dragster moves with velocity 10 m/s from \(t = 0\) s to \(t = 2\) s and then linearly increases from 10 m/s to 20 m/s between \(t = 2\) s and \(t = 4\) s. What total distance does it travel from \(t = 0\) s to \(t = 4\) s?

💡 Difficulty: medium | ✅ Correct: C

Q3. A particle's velocity is \(v(t) = t^2 - 4t + 3\) m/s for \(t \ge 0\). At what time does the particle travel exactly 10 m from \(t = 0\)?

💡 Difficulty: hard | ✅ Correct: B
