A balloon is moving up from the ground in such a way that its acceleration is linearly decreasing with its height above the ground. It starts from the ground with acceleration 4 m/s2 and with zero initial velocity. Its acceleration becomes zero at a height 3 m. The speed of the balloon at a height 1.5 m is
(a)	4 m/s	(b)	8 m/s	(c)	6 m/s	(d)	3 m/s
