True or False An object moves in a circular path with constant speed v. Its velocity is constant, but its centripetal acceleration is changing.

In a circular motion, if an object has a speed of 35.5m/s, and radius of the circular path is 45.2 m, what is the centripetal acceleration in m/s?

A jet fighter flying at 300 m/s (just below the speed of sound) makes a turn of radius 2.55 km. (a) What is its centripetal acceleration in gs? (b) Suppose the pilot makes an emergency turn to avoid an approaching missile, subjecting himself to a centripetal acceleration of 10 gs, while flying at 565 m/s (supersonic). What is the radius, in km, of his turn? (This must be short-lived because fighter planes can only briefly endure such large accelerations without serious damage, and the pilot will soon black out at 10 gs.)

An airplane makes a gradual 270° turn (heading goes from north to west to south to east) while flying at a constant speed of 212 m/s and maintaining the same altitude. The process takes 15.6 seconds to complete and the radius of the turn is 2105 m. For this turn, the magnitude of the average acceleration of the plane is?
