JEE Main 2025 — Center of Mass Momentum and Collision Question with Solution
JEE Main 2025 (3 Apr Shift 2)
Question
Consider two blocks A and B of masses and that are placed on a frictionless table. The block A moves with a constant speed towards the block B kept at rest. A spring with spring constant is attached with the block B as shown in the figure. After the collision, suppose that the blocks A and B, along with the spring in constant compression state, move together, then the compression in the spring is, (Neglect the mass of the spring)
