Stones are thrown from the balloon which is moving upwards with acceleration = 0.2 m/s2
 
hence acceleration of stone as seen from balloon = 9.8+0.2 m/s2 = 10  m/s2
 
Distance travelled by first balloon for 3.5 s = (1/2)×10×3.5×3.5 = 61.25 m
 
Distance travelled by second balloon for 1.5 s = (1/2)×10×1.5×1.5 = 11.25 m
 
difference in distance = 61.25 - 11.25 = 50 m
