Verified Answer :

For this problem we are going to use: 

a = v^2 / r 

-or- 

v = sqrt[ ar ] 

We know: 
a = 98 m/s^2 
r = 12 m 

Plug these in and solve for v: 

v = sqrt[ 98 12 ] 
v = 34.29 m/s 

So the driver is moving at 34.29 m/s when whe experiences 10g's

We have that he riders speed is is mathematically given as

  • v =34.3 m/s

From the question we are told

the length of the centrifuge arm is 12 m , what speed is the rider moving when she experiences 10 g's ?

Speed

Generally the equation for the acceleration  is mathematically given as

a = v^2/r

Therefore

9.8 = v^2/12

v =34.3 m/s

Therefore

The riders speed is

  • v =34.3 m/s
