Question

Two bodies of mass 1 kg are moving in a straight line but opposite in direction with the same velocity of 2 m/s they collide with each other and stick to each other after collision what is the common velocity of these bodies after collision

Answer 1

Hey Mate!!

Answer:0m/s

Here's the Explanation

we have Bodies Of same Mass 1kg

And They Are Traveling With a speed of 2 m/s

So When They collide,

.

.

.

.

F1=ma

F1=1*2

F1=2N

F2=1*2

F2=2N

So when They Collide Their Force Will Cancel Each Other

By Newton's 3rd Law Of Motion.

So Velocity Becomes Zero

Hope it Helps
