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?
Answered by R_Scott
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
Answered by 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.
