Hi everyone,
I would really appreciate any advice on how to go about solving the following problem. I'm supposed to investigate it in a report.
A paratrooper who jumps out of an aircraft moving in horizontal flight initially has the same horizontal velocity as the aircraft. However, immediately, forces begin to change this. The drag force begins to slow him down, but at the same time the force of gravity tends to speed him up. It has been claimed that for any specified launching speed, the speed of the paratrooper will pass through a minimum value less than either the launching speed or the terminal speed. Obviously, if he is high enough, the paratrooper should wait for the minimum speed to lessen the shock when the parachute opens. Investigate this claim.
d=Vi(t) + 1/2a(t^2), v_term = (mg/k)^(1/3)
I'm not completely sure how to approach this question, but I started by looking at the equations for kinematics and terminal velocity. btw I'm in Grade 12, if that helps.
