A 1500 kg weather rocket accelerates upward at 10\;{\rm m}/{\rm s}^{2} . It explodes 2.0 s after liftoff and breaks intotwo fragments, one twice as massive as the other. Photos revealthat the lighter fragment traveled straight up and reached amaximum
What was the speed of the heavier fragmentjust after the explosion?
