Answer:
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
