Just as it has reached an upward speed of 5.00 m/s during a vertical launch, a rocket explodes into two pieces. Photographs of the explosion reveal that the lower piece, with a mass one-fourth that of the upper piece, was moving downward at 3.00 m/s the instant after the explosion.

Part 1: Find the speed of the upper piece just after the explosion.

Part2: How high does the upper piece go above the point where the explosion occurred?
