In a closed subway car, a girl holds a helium-filled balloon by a string. While the car is travelling at constant velocity, the string of the balloon in exactly vertical.

Suppose that when the car is breaking the string is inclined at an angle of 20 degrees with the vertical and remains there. What is the acceleration of the car?
