    Linear motion

    A model of a helicopter rotor has four blades, each of length 3.10 m from the central shaft to the blade tip. The model is rotated in a wind tunnel at a rotational speed of 490 rev/min.

    A) What is the linear speed of the blade tip?

    B) What is the radial acceleration of the blade tip expressed as a multiple of the acceleration of gravity, g?
