If a ball of mass 2kg that is moving, hits a stationary ball of mass 1kg, in an inelastic collision. How would we find which ball moves faster after the collision?
We have
mass of 2kg ball * velocity of 2kg ball (intial) = mass of 2kg ball * velocity of 2kg ball (after) + mass of 1kg ball * velocity of 1kg ball (after).
$m_{2kg}*v_{initial} = m_{2kg}*u_{2kg} + m_{1kg}*u_{1kg}$
How would we work out the velocity for each ball after collision?
Are they just distributed in proportion to the masses, i.e. would the velocity of the 1kg ball be twice the velocity of the 2kg ball?
