How fast does water flow from a hole at the bottom of a

ANSWER:STEP 1:-Let’s take the respective masses and velocities of the two ball are, m 1 100 g = 0.1 kg m = 300 g = 0.3 kg 2 v = 10 m/s 1 v = 0 m/s 2 A) If the collision is completely elastic:We know that if the collision is elastic, then the momentum and kinetic energy of the wholesystem will be conserved during the process.So, let’s impose these conditions.Momentum conservation says, m 1 1 m v =2 2v + m 1 1------2 2------------(1)And kinetic energy conservation says, 1/2 m v 2+ 1/2 m v 2 = 1/2 m v + 1/2 m v -------------
