You've taken your neighbor's young child to the carnival to ride the rides. she wants to ride the rocket. eight rocket-shaped cars hang by chains from the outside edge of a large steel disk. a vertical axle through the center of the ride turns the disk, causing the cars to revolve in a circle. you've just finished taking physics, so you decide to figure out the speed of the cars while you wait. you estimate that the disk is 6 m in diameter and the chains are 6 m long. the ride takes 10 s to reach full speed, then the cars swing out until the chains are 25 degrees from vertical.
what is the car's speed?

v = 5.01 m/s

Explanation:

from the question we have:

diameter of the disk (d) = 6 m

length of the chains (L) = 6 m

time (t) = 10 s

angler formed (θ) = 25 degrees

we first have to calculate the total radius formed while the ride is in motion

total radius = radius of the steel disk + distance of the cars from the outside edge of the disk while in motion

total radius = () + ( L × sin 25 )

(remember the cars swing out until the chains are at 25 degrees to the horizontal thereby forming a triangle with the length of the chain being the hypotenuse and the  distance of the cars from the outside edge of the disk while in motion being the opposite side to the angle formed)

total radius = () + ( 6 × sin 25 )

total radius = 3 + 2.5 = 5 m

now we can apply the formula below to get the velocity

centripetal force (F) =

where

we now have

m x g x tan 25 =  

g x tan25 =

9.8 x tan 25 =

v^{2} = 5.5 x 9.8 x tan 25 = 25.13

v = 5.01 m/s
