Question

Q16. A ball of mass m, moving with a speed of 2vo, collides inelastically with 3
identical ball at rest. Show that
(ii) For a general collsion, the angle between the two velocities of
scattered balls is less than 90°.​

Answer 1

Explanation:

ball of mass m, moving with a speed 2v0, collides inelastically (e > 0) with an identical ball at rest. Show that

(a) For head-on collision, both the balls move forward.

(b) For a general collision, the angle between the two velocities of scattered balls is less than 90°.
