A billiard ball traveling at 3.4 m/s has an elastic head-on collision with a billiard ball of equal mass that is initially at re
Tpy6a [65]

Answer:

Explanation:

Given

Initial velocity of first billiard ball u_1=3.4\ m/s

Initial velocity of second billiard ball u_2=0\ m/s

After collision first ball comes to rest

suppose m is the mass of both the balls

Conserving momentum to get the speed of second ball after collision

Initial momentum P_i=mu_1+mu_2=m\cdot 3.4+0

Final momentum P_f=mv_1+mv_2

where v_1 and v_2 are the speed of first and second ball respectively

P_i=P_f

m\cdot 3.4+0=0+m\cdot v_2

v_2=3.4\ m/s

thus speed of second ball after collision is equal to speed of first ball before collision
