Challenge Problems
Push your limits with advanced challenges
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.
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.
