A bullet is fired horizontally and gets embedded in a block kept on a table. If the table is frictionless, then :

only momentum is conserved. only potential energy is conserved. both (a) and (b). only K.E. is conserved.

both (a) and (b).

A bullet is fired horizontally and gets embedded in a block kept on a table. If the table is frictionless, then both linear momentum and potential energy are conserved.
