Challenge Problems
Push your limits with challenges.
Question 1
A 500 kg car traveling at 15 m/s hits a tree. Calculate the impulse experienced by the car in the crash if it comes to a complete stop.
💡 Hint: Consider what happens to the speed during the collision.
Question 2
If the coefficient of restitution between two colliding objects is 0.5, what does that say about their collision energy and how does it affect their velocities post-collision?
💡 Hint: Think about how some of the energy is transformed rather than conserved.
