Two people jump out of an airplane. They hold on to each other while falling straight down at a shared terminal speed of 60.7 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):
v1x: 4.43 m/s
v1y: 4.75 m/s
v1z: 60.7 m/s
What are the x- and y-components of the velocity of the second skydiver, whose mass is 57.7 kg, immediately after separation?
What is the change in kinetic energy of the system?
