Each of the space shuttle’s main engines is fed liquid hydrogen by a high-pressure pump. Turbine blades inside the pump rotate at 617 rev/s. A point on one of the blades traces out a circle with a radius of 0.020 m as the blade rotates.
(a) What is the magnitude of the centripetal acceleration that the blade must sustain at this point?
(b) Express this acceleration as a multiple of g = 9.80 m/s^2
Please post the steps you did to solve it too, thanks!

centripetal acceleration= w^2 r
change rev/sec to rad/sec
