For inelastic collsion between two spherical rigid bodies

Options

A. the total kinetic energy is conserved
B. the total potential energ is conserved
C. the linear momentum is not conserved
D. the linear momentum is conserved

Answer

D

Explanation

In a perfectly inelastic collosion, the two bodies start moving with a common velocity after collision. This is oberved in (a), (b) and (d) . But striking of two glass balls is not perfectly inelastic.
