Center of Mass question

2024 · 8 Apr · Shift 1 · Q61

JEE MainPhysicsCenter of MassMCQ+4 / −1
A stationary particle breaks into two parts of masses mAm_AmA​ and mBm_BmB​ which move with velocities vAv_AvA​ and vBv_BvB​ respectively. The ratio of their kinetic energies (KB:KA)\left(K_B: K_A\right)(KB​:KA​) is :
  1. A
    vB:vAv_B: v_AvB​:vA​
  2. B
    1:11: 11:1
  3. C
    mBvB:mAvAm_B v_B: m_A v_AmB​vB​:mA​vA​
  4. D
