# Question: HALO stands for High Altitude Low Opening. In a HALO jump the parachutist jumps from a height between 5 and 10 km above the ground – Free Chegg Question Answer

`Transcribed text From Image: HALO stands for High Altitude Low Opening. In a HALO jump the parachutist jumps from a height between 5 and 10 km above the ground, but doesn't open the parachute until a height of 1 km or less. Since the fall is long, the parachutist Tow reaches terminal velocity. The velocity as a function of time is shown in the figure. 90 adid 80 70 5 60 STS 50 v (m/s) 40 nge 30 ngle f 15 t the 20 thing 10 0 0 2 12 16 10 20 10 tis) like U acce f the 14 mau5 1 The velocity as a function of time has the following form: v(t) = v tanh((g/v.)t), where g is the gravitational acceleration (9.81 m/s2), V is the terminal velocity, and tanh is the hyperbolic tangent function. For simplicity the initial velocity of the ght T parachutist is assumed to be zero. A non-zero inital velocity would make this formula unnecessarily complicated. What is the terminal velocity reached by the parachutist? A horizontal line is drawn in the graph as a guide.
