A car is travelling in steady rain with constant acceleration in a straight line. When it begins to move the driver sees that the raindrops make track at an angle of \(37^{\circ}\) with the vertical on the side window. After \(20 sec\)., the raindrops make track at an angle of \(53^{\circ}\) with vertical in same direction. Find the acceleration of the car in \(cm / s ^2\). Rain is falling at \(3 m / s\).
