A jet fighter flying at 300 m/s (just below the speed of sound) makes a turn of radius 2.25 km. (a) what is its centripetal acceleration in gs?

The centripetal acceleration is calculated by dividing the square of the velocity by the radius of the circular path. That is,

a = v²/r

Substituting the known values with consistent units,

a = (300 m/s) ² / (2.25 x 10^3 m)

Simplifying,

a = 40 m/s²

Hence, the centripetal acceleration is equal to 40 m/s².
