Two skydivers are holding on to each other while falling straight down at a common terminal speed of 57.1 m/s. Suddenly, they push away from each other. Immediately after separation, the first skydiver (who has a mass of 89.3 kg) has the following velocity components (with "straight down" corresponding to the positive z-axis):
What are the x- and y-components of the velocity of the second skydiver, whose mass is 52.2 kg, immediately after separation?
What is the change in kinetic energy of the system?
