here is the easy method ,consider the relative motion of the bodies, since the boy on the car the horizantal speed of the ball will be same as that of the carat the instant of throwing .Now
v = u +at
0 = 9.8 -9.8t
t = 1
therefore total time taken to reach ground is 2 s
now since the car is accln at 1m/s2 , in 2s it would cover 2m
