Answer:
v₁ =0.19 m/s and v₂ = 0.18 m/s
Explanation:
By conservation of energy and conservation of momentum we can find the velocity of each object after the collision:
<u>Momentum:</u>
Before (b) = After (a)
(1)
<u>Energy:</u>
Before (b) = After (a)
(2)
<u>From equation (1) we have:</u>
(3)
<u>Now, by entering equation (3) into (2) we have: </u>
(4)
By solving equation (4) for , we will have two values for
We will take the average of both values:
Now, by introducing this value into equation (3) we can find :
Therefore, the velocity of object 1 and object 2 after the collision is 0.19 m/s and 0.18 m/s, respectively.
I hope it helps you!
