A train is rounding a circular curve whose radius is 2.00 multiply.gif 102 m. At one instant, the train has an angular acceleration of 1.50 multiply.gif 10-3 rad/s2 and an angular speed of 0.0500 rad/s.
(a) Find the magnitude of the total acceleration (centripetal plus tangential) of the train.
(b) Determine the angle (in degrees) of the total acceleration relative to the radial direction.
