a race car starting from rest accelerates at a constant rate of 5m/s2

1.	a race car starting from rest accelerates at a constant rate of 5m/s2 for some time after which it deacelerates with 10m/s2 and comes to rest if total time required is 9 sec then maximum speed aquired by the car is
Answer» 30Explanation:V MAX =(a×b×T)/(a+b) where a=acceleration,b=deceleration,T=total TIME so VMAX =(5×10×9)/(5+10) =450/15 =30
