Answer: The final velocity will be equal to the initial velocity at t= 8 s.
Explanation:
We know that,
The equation of line
According to figure
We know that,
The velocity is
On integrating
Here, u = initial velocity
Now, when v = u then the time will be
Hence, The final velocity will be equal to the initial velocity at t= 8 s.
