Therefore the solution of this question is the velocity of roller coaster  after 3 second is 22 m/s

What is velocity?

The rate at which an object's position is changing as perceived from a given point of view and as described by a certain unit of time is known as its velocity.

Here,

The speed of  roller coaster is 4m/s

The acceleration of  roller coaster is 6m/s2

So,

we have to find the velocity after 3 second

thus we use the formula v=u + at

Putting values

=> v = 4 +6*3

=> v = 4 + 18

=> v = 22 m/s

Therefore the velocity of roller coaster  after 3 second is 22 m/s
