At a given instant train E has a speed of 20m/s and an acceleration of 14m/s^2 acting in the direction shown (75 degrees to the left of the track).
Find the magnitdue of the acceleration when it reaches point A (half way down the slope) where the speed is Va = 10m/s, height is 36m, distance of 60m from end of slope, and rate increaseing at Va = 3 m/s^2.
