A fireworks rocket is fired vertically upward. At its maximum height of 80.0 m it explodes into two pieces, one with mass of 1.40 kg and the other one with mass 0.28 kg. In the explosion, 860 J of chemical energy is converted to kinetic energy of the two fragments.
Required:
a. What is the speed of each fragment just after the explosion?
b. It is observed that the two fragments hit the ground at the same time. What is the distance between the points on the ground where they land? Assume that the ground is level and air resistance can be ignored.
