Question
In a collinear collision, a particle with an initial speed v0 strikes a stationary particle of the same mass. If the final total kinetic energy is 50 % greater than the original kinetic energy, the magnitude of the relative velocity between the two particles, after collision, is :
Options
A.
B.
C.
D.
Solution
initial
...(1)
from momentum conservation
mv0 = m(v1 + v2) ...(2)
(v1 + v2)2 = v02
(v1 - v2)2 =
v1 - v2 =
