Two skydivers are holding on to each other while falling straight down at a common terminal speed of 51.10m/s. Suddenly, they push away from each other. Immediately after the separation, the first skydiver, who has a mass of m1=83.80kg, has a velocity of v1 with the following components ("straight down" corresponds to the positive Z-axis).

v1,x=5.430m/sv1,y=3.750m/sv1,z=51.10m/sv1

Assuming that there are no horizontal forces of air resistance acting on the skydivers,

(a) What are the x, y- and z-components of the velocity v2 of the second skydiver, whose mass is m2=52.20kg, immediately after the separation?

(b) What is the change in kinetic energy of the system KsystemKsystem?
