![Two skydivers are holding on to each other while falling straight down at a common terminal speed of 51.10 m/s.
Suddenly, they push away from each other. Immediately after the separation, the first skydiver, who has a mass of
m₁ = 83.80 kg, has a velocity of with the following components ("straight down" corresponds to the positive z-
axis).
V1,2 = 5.430 m/s V₁,y = 3.750 m/s v₁,2 = 51.10 m/s
Assuming that there are no horizontal forces of air resistance acting on the skydivers,
V2
(a) What are the x-, y- and z-components of the velocity of the second skydiver, whose mass is m₂ = 52.20 kg,
immediately after the separation?
