    Answer:

    Linear velocity (in m/s) = 1.6 m/s

    Explanation:

    Given:

    Length of rotational plane = 80 cm

    Angular  velocity of the rod = 4rad/s

    Find:

    Linear velocity (in m/s)

    Computation:

    Radius from mid point C = Length of rotational plane / 2

    Radius from mid point C = 80 / 2

    Radius from mid point C = 40 cm

    Radius from mid point C = 0.4 m

    Linear velocity (in m/s) = Angular  velocity of the rod x Radius from mid point C

    Linear velocity (in m/s) = 0.4 x 4

    Linear velocity (in m/s) = 1.6 m/s
