A bus is moving forward on a horizontal road. It slows down with an acceleration of 2.00 m.s^-2. This causes a metal ball of mass 0.500 kg suspended by a string from the roof of the bus to swing and make an angle from the vertical. Calculate:

(a) The resultant force acting on the ball.

(b) The string tension.

(c) The value of the angle .
