Classical Mechanics
Level
5
A ball with the initial velocity \(u = 3i + 4j \) collides with the smooth wall and rebounds with the final velocity \(v = 2i - 3j\). Find the coefficient of restitution for the collision.
Your answer can be represented as \( e \) = \(\dfrac{a}{b}\), where a and b are coprime numbers.
Enter your answer as \(a + b\).
