Answer:
The minimum length for the slip road = 100 meter.
Explanation:
We have equation of motion, [tex]v^2=u^2+2as[/tex], where u is the initial velocity, u is the final velocity, s is the displacement and a is the acceleration.
In this case initial velocity = 10 m/s, final velocity = 30 m/s and acceleration = [tex]4m/s^2[/tex], we need to find displacement.
Substituting
[tex]30^2=10^2+2*4*s\\ \\ 800=8s\\ \\ s=100meter[/tex]
The minimum length for the slip road = 100 meter.
