An inelastic collision takes place between ball of known masses, just before the collision one of the ball is moving with a known velocity while the other is stationary. Which of the following physical quantities can be determined from the information given?
speed of each of the ball after collision
kinetic energy of each ball after collision
total momentum of the ball after collision
total momentum of the two ball after collision
mutual forces excerted by the balls

For inelastic collision
m1u1 + m2u2 = (m1+m2)V
If m2 is stationary
m1u1=(m1+m2)v
the total momentum of both balls after collision is
(m1+m2)V
In an inelastic collision, the bodies stick together after the collision therefore having a common velocity so we can't get the "speed of each of the balls after collision" as suggested in option A or the "Kinetic energy of each ball after collision" in option B:
In conclusion, the answer is D
I'm glad to see so many students choosing the right answer. It shows learning is taking place 👍
