A 0.5 kg ball travelling at a velocity of 1 m/s collides with a 1.5 kg ball at rest, calculate the
velocity after the collision.

0.25m/s

Explanation:

Mass, m1 = 0.5kg

m2= 1.5kg

Velocity before collision for mass 1, u1 = 1m/s

Velocity before collision for mass 2, u2 = 0m/s because it is at rest.

Velocity after collision, V = ?

From law of conservation of linear momentum

Sum of momentum before collision = sum of momentum after collision.

Remember momentum = mass x velocity

Therefore,

m1u1 +m2u2 = (m1 + m2)V

0.5x1 + 1.5x0 = (1.5+0.5)V

0.5+0 = 2V

2V = 0.5

Divide both sides by 2

V = 0.5/2

V = 0.25m/s
