Teaching MPPSC Assistant Professor Mock Test Series 2025 Physics Center of Mass and Linear Momentum Collisions
A ball of mass 3 kg moving with a velocity of 4 m/s undergoes a perfectly elasticĀ collision with a stationary ball. After the impact is over, the kinetic energy of the 3 kg ball is 9 J. Then the mass of the stationary ball is -
1
1 kg
2
0.72 kg
3
0.56 kg
4
0.33 kg
