    Please provide me step by step solution.

    A mass (M=3kg) is attached to a weightless cord of length L=2m is spun in a circular path. θ=85°.

    a) Draw the free body diagram for the mass at the point in time shown in the figure above.

    b) What is the tension in the cord?


    c) What is the tangential velocity of the mass?

    d) How long does it take the mass to make one full rotation?
