Not sure of the number, but it is about a weather rocket that explodes.
A 1500 kg weather rocket accelerates upward at 10\;{\rm m}/{\rm s}^{2} . It explodes 2.0 s after liftoff and breaks into two fragments, one twice as massive as the other. Photos reveal that the lighter fragment traveled straight up and reached a maximum height of 530 m.
That is the problem.
What was the speed of the heavier fragment just after the explosion?
That is the question.
I solved and got 20.96 m/s. It gives me this error:
You are close. You may have made a rounding error or used the wrong number of significant figures.
Help! What is the right answer?
