Answer:
The value is 
Explanation:
From the question we are told that
The initial speed of the roller coaster is 
The length of the hill is 
The acceleration of the roller coaster is 
Generally the acceleration is mathematically represented as

Here
is the initial time which is equal to zero
is the final velocity which is mathematically represented as

So




Solving this using quadratic formula we obtain


Generally time cannot be negative so

Generally the final velocity is mathematically represented as
