Question

6. Two bodies of masses 0.2 kg and 0.1 kg moving in the same direction on a
straight line with velocities 0.6 ms
1 and 0.4 ms
respectively, suffer
head-on collision. Calculate their velocities after collision.
Ans: V11=0.47 m s -1, V2r=0.67 ms -1​

Answer 1

Answer:

Mass of object 1, m = 0.2 kg

Mass of object 2, m' = 0.1 kg

Initial speed of object 1, u = 0.6 m/s

Initial speed of object 2, u' = 0.4 m/s

To find,

The final velocity after the collision.

Explanation:

et V is the common velocity of the objects after the collision. Using the conservation of linear momentum such that,

So, the final velocity after the collision is 0.54 m/s.
