Answer 1

Answer:

Explanation:

go on increasing with time.

Given x=ae−αt+beβt

Velocity = displacement / time = v=dxdt=−aαe−αt+bβeβt

As you can see, velocity is dependent of α and β, and does not drop to zero when α=β

Now as t increases, −aαe−α decreases and bβeβ increases → velocity goes on increasing with time.
