A 1420 kg weather rocket accelerates upward at 20 m/s2. It explodes2.0 s after liftoff and breaks into two fragments, one twice asmassive as the other. Photos reveal that the lighter fragmenttraveled straight up and reached a maximum height of 530 m. Whatwere the speed and direction of the heavier fragment just after theexplosion?

I got upward direction, which is correct.
I tried 51, 72.8 and 72.06 m/s for the speed,
which have been noted incorrect by the ruling
