JEE Main 2025 (Online) 3rd April Evening Shift Physics - Center of Mass and Collision Question 1 EnglishConsider two blocks A and B of masses m1=10 kgm_1=10 \mathrm{~kg}m1​=10 kg and m2=5 kg\mathrm{m}_2=5 \mathrm{~kg}m2​=5 kg that are placed on a frictionless table. The block A moves with a constant speed v=3 m/sv=3 \mathrm{~m} / \mathrm{s}v=3 m/s towards the block B kept at rest. A spring with spring constant k=3000 N/m\mathrm{k}=3000 \mathrm{~N} / \mathrm{m}k=3000 N/m 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)
