estion 3 es remaining 3 A billiard ball with mass 6.7 kg is shot due west at 9.5 m/s. The ball o Assuming a frictionless table, what is the magnitude of the final velocity of the second billiard ball in m/s due Answer of mass 6.7 kg The second billiard ball travels due west, the same direction as the first billiard ball was traveling ints out of 1,00 Flag question Check

Solution

Given, m1 = 6.7 kg , m2 = 6.7 kg

u1 = 9.5m/s ( due west ) , u2 = 0 ( at rest) ( before collision)

Let v2 be the speed of the second ball after collision

Since the collision is an elastic collision and the masses of both the objects are same , the speed of both the objects are interchanged after the collision since both the momentum and energy are conserved

v2 = u1

So, v2 = 9.5 m/s (due west)

Therefore , answer) 9.5 m/s
