Body A of mass 4m moving with speed u collides with another body B of mass 2m, at rest. The collision is head on and elastic in nature. After the collision the fraction of energy lost by the colliding body A is : at rest. The collision is head on and elastic in nature. After the collision the fraction of energy lost by the colliding body A is : Body A of mass 4m moving with speed u collides with another body B of mass 2m August 28, 2020 Category: Chapter 8 - Collisions , NEET Last 32 Years Solved 1988 - 2019 Physics and Chemistry Video Solutions , Physics , Facebook Messenger WhatsApp Share this:TwitterFacebook Related A body of mass �=0.1 �� has an initial velocity of 3 ^ i �/�. It collides elastically with another body, B of the mass which has an initial velocity of 5 ^ j �/�. After collision, A moves with a velocity v = 4 ( ^ i + ^ j ) �/�. The energy of B after collision is written as (�/10) �, the value of � isBlocks 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 8 m starts moving the total energy loss is p% of the original energy. Value of ‘p’ is close toConsider a uniform rod of mass M = 4m and length l pivoted about its centre. A mass m moving with velocity v making angle θ = π/4 to the rod's long axis collides with one end of the rod and sticks to it. The angular speed of the rod-mass system just after the collision is
