In this video, we solve a classic relative motion and acceleration problem involving a speeding motorist and a police officer in pursuit.
A car moves at 31 m/s, passes a stationary police officer, and 2.5 seconds later the officer accelerates at 3.6 m/s² to catch up.
We carefully break down:
✅ How to write position equations for both vehicles
✅ How to handle delayed motion (reaction time)
✅ How to equate position functions to find the catch-up time
✅ How to determine the officer’s speed at overtaking
✅ How maximum speed limits change the solution
✅ How to sketch and interpret x–t graphs
This problem is perfect for students studying:
Kinematics
Relative Motion
Constant Acceleration
Motion Graphs (Position vs Time)
High School & A-Level Physics
If you're preparing for exams, this is the kind of structured solution that earns full marks.
