Question

A body (A) of mass 100 g and another body (B) of
mass 400 g approach each other with velocities of
100 cm.s-1 and 10 cm.s-1 respectively. After a head-
on collision, the bodies coalesce. After collision, find the direction of motion of the combined mass and the displacement in 10s​

Answer 1

Explanation:

use the formula of law of conservation of mass then use s=ut+1/2at² u get urs answer
