JEE MainPhysicsCenter of MassMCQ+4 / −1
Blocks of masses m, 2m, 4m and 8m are arranged in a line on a frictionless floor. Another block of mass m, moving with speed v along the same line (see figure) collides with mass m in perfectly inelastic manner. All the subsequent collisions are also perfectly inelastic. By the time the last block of mass 8m starts moving the total energy loss is p% of the original energy. Value of 'p' is close to : JEE Main 2020 (Online) 4th September Morning Slot Physics - Center of Mass and Collision Question 70 English
