Two objects each of mass 1.5 kg

Asked by maham237 @ 03/01/2021 in Physics viewed by 291 People

2 objects each of mass 1.5kg are moving in the same straight line but in the opposite directions. The velocity of each object is 2.5m/s before collision, during which they stick together. What will be the velocity of combined object after collision?

Answered by maham237 @ 03/01/2021

Answer:

0 m/s

Explanation:

Momentum before = momentum after

m₁ u₁ + m₂ u₂ = (m₁ + m₂) v

(1.5 kg) (2.5 m/s) + (1.5 kg) (-2.5 m/s) = (1.5 kg + 1.5 kg) v

v = 0 m/s
