Question

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

Answer 1

Answer:

0

Explanation:

Since both the weight and the velocity is same for both of the objects, both of the objects will be at rest after collision. Notify me if I am wrong so that i can correct my mistakes and give a thanks or brainliest if my answer satisfied you.

Answer 2

Answer:

Given : m 1 =m 2 =1.5 kg u

1 =2.5 ms −1u 2

=2.5 ms −1Total mass of the combined system, M=m 1 +m 2 =2×1.5=3kg

Let the velocity of the combined system after the collision be v

Applying conservation of momentum before and after the collision :m 1 u 1 −m 2 u 2 =Mv1.5×2.5−1.5×2.5=3v ⟹v=0
