Dynamics reactant forces

    A man having the mass of 75 kg sits in the chair which
    is pin-connected to the frame BC. If the man is always seated in
    an upright position, determine the horizontal and vertical
    reactions of the chair on the man at the instant theta = 45

    . At this
    instant he has a speed of 6 m/s, which is increasing at 0.5 m/s^2

    if you can answer this great, but I am looking for someone who can more less give me a step by step to solve this. Thanks for the hlep

    Write down all the equations of motion you know that might be useful in solving this.
