A train is moving along a straight horizontal track. A pendulum suspended from the roof of one of the carriages of train is inclined at four degree to the vertical. Calculate tge acceleration of train

  • Physics -

    Le A be the angle of inclination (4 degrees).
    T = string tension force.
    Write the vertical and horizontal Newton's second law equations
    W = M g = T cos A
    M a = T sin A
    Eliminate T

    a/g = tan A = 0.0699
    Solve for a
