The final velocity of the two objects after the collision is determined as 4 m/s.
Final velocity of the two objects after the collision
The final velocity of the two objects after the collision is determined from the principle of conservation of linear momentum as shown below;
m₁u₁ + m₂u₂ = v(m₁ + m₂)
where;
- m1 = 2 kg
- u1 = 5 m/s
- m2 = 0.5 kg
- u2 = 0
- v = ?
2(5) + 0.5(0) = v(2 + 0.5)
10 = 2.5v
v = 10/2.5
v = 4 m/s
The complete question is below:
A body of mass 2kg moving with velocity of 5m/s collides with a stationary body of mas 500g. if the two bodies move together after impact. Calculate the magnitude of their common velocity.
