How fast (in rpm) must a centrifuge rotate if a particle 5.50 cm from the axis of rotation is to experience an acceleration of 119000 g's? if the answer has 4 digits or more, enter it without commas, e. g. 13500.

If a spring has a k value of 100 newtons per meter and it is stretched 0.50 meters, what is the restoring force of the spring?

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
