Each of the space shuttles main engines is fed liquid hydrogen by a high-pressure pump. Turbine blades

Question:

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/s2.
