Question
a black ball of mass 2kg moving at velocity 10m/s collide with a stationary white ball of mass 3kg.find their common velocity if they stick together after collision?
Answers

the black ball's initial momentum is now shared by both balls
find the initial momentum (it is conserved)
use the combined mass to find the new velocity

henry2,
Given:
M1 = 2 kg, V1 = 10 m/s.
M2 = 3 kg, V2 = 0.
V3 = Velocity of M1 and M2 after collision.
p before = p after.
M1*V1 + M2*V2 = M1*V3 + M2*V3.
2 * 10 + 3 * 0 = 2*V3 + 3*V3,
V3 = m/s.
M1 = 2 kg, V1 = 10 m/s.
M2 = 3 kg, V2 = 0.
V3 = Velocity of M1 and M2 after collision.
p before = p after.
M1*V1 + M2*V2 = M1*V3 + M2*V3.
2 * 10 + 3 * 0 = 2*V3 + 3*V3,
V3 = m/s.
