problem2) A centrifugal pump with smooth radial vanes rotates in horizontal plane with constant angular velocity, w. Determine the magnitude of force exerted by a vane on a particle of mass m as it moves out along the vane. The particle is introduced at r = r0 with no angular velocity. Suppose there is no shear (i.e., friction) force between the particle and vane.
