I NEED HELP ASAP:

What is the centripetal acceleration of a jet making a turn with a radius of 1.00 km at a speed of 343 m/s?

The centripetal acceleration of the jet is equal to the square of its speed divided by the radius of the turn, so the centripetal acceleration of the jet is equal to (343 m/s)^2 / (1.00 km) = 117700 m/s^2.
