engineering recuitment DRDO CEPTAM STA B Tier I (Sr. Technical Assistant) Mock Test 2022 Engineering Mechanics Kinematics and Kinetics Collision of Bodies
In elastic collisions of bodies:
1
both of the momentum and total kinetic energy are conserved.
2
neither momentum of the colliding bodies nor the total kinetic energy are recoverable.
3
only the total kinetic energy is conserved.
4
only the total momentum of the colliding objects is conserved
