W, because as time is moving up at a consistent rate the speed is as well, creating the straight line.
Answer:
11.4 m/s
Explanation:
The expression for the Centripetal acceleration is :

Where, a is the accleration
v is the velocity around circumference of circle
R is radius of circle
In the given question,
a = g = Acceleration due to gravity as the car is at top = 
v = ?
R = 13.2 m
So,


<u>v = 11.4 m/s</u>
