Two skydivers are holding on to each other while falling straight down at a common terminal speed of 51.1 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):

V1x=4.93 m/s V1y=4.25 m/s V1z=51.1 m/s

What are the x- and y-components of the velocity of the second skydiver, whose mass is 63.2 kg, immediately after separation?
