Question

Derive an expression for velocities of two bodies after elastic collision in 1d

Answer 1

Explanation:

just before collision pi = pf i.e momentum conservation

m1u1-m2u2=m1v1+m2v2.......(1)

e=1

u1+u2=v2-v1....(2)

from equation 2 get v1 and v2 then put values of v1 & v2 in equation first
