Question

A massive ball moving with speed v collides head on with a fine ball having mass very much smaller than the mass of first ball.The collision is elastic. Then, immediately after the impact, the second ball will move with a speed approximately equal to

Answer 1

m1>m2 ; Velocity of massive ball-v

a head-on elastic collision where the projectile is much more massive than the target, the velocity of the target particle after the collision will be about twice that of the projectile and the projectile velocity will be essentially unchanged. So, the second ball will move with a speed approximately equal to 2v.
