Question

To withstand ‘g-forces’ of up to 10 g’s, caused by suddenly pulling out of a steep dive, fighter jet pilots train on a ‘human centrifuge.’ If the length of the centrifuge arm is 12 m, at what speed is the rider moving when she experiences 10 g’s?

Answer 1

34.292 m/s

Step-by-step explanation:

When plane dives the gravitational acceleration becomes 10 times extra i-e

acceleration a = g= 10g's=10 ×9.8= 98 m/sec2

radius of dive circle = 12 m

v= speed= ?

Using

`a= (v^(2) )/(r)`

==>
`v^(2)` = a × r = 98 × 12 = 1176
`((m)/(s)) ^(2)`

==> v=
`\sqrt{1176((m)/(s) )^(2) }`

==> v= 34.292 m/s
