Physics Velocity question?
Hi there I need some help with this question.
I understand the basic idea of it but I'm unsure how to calculate the advancing rocket's velocity as well as the man's own falling velocity given these equations.
y=yo + voy*t+.5ay*t
vy=voy+ay*t
vy^2=voy^2+2ay* change of y
If it was just the man falling to the ground then the first equation would be used with y=o as the ground. Then I could use the quadratic equation to solve for time.

Mitch is skydiving. He jumps out of a plane and reaches a terminal velocity (constant velocity) of 20 m/s. When he is 1000 m above the ground, Skid, standing directly below Mitch, fires a rocket launcher at Mitch. The rocket has an initial velocity of 125 m/s.
a) How much time does Mitch have to figure out how to survive this predicament?
b) Assuming Mitch does not have his wits about him, at what location above the ground will the rocket intersect with him?
