I have posted a link to this topic so the OP can see my work.Differential Equation Help Please?

According to a newspaper account, a paratrooper survived a training jump from 1200 ft when his parachute failed to open but provided some air resistance by flapping unopened in the wind. Allegedly he hit the ground at 100 mph after falling for 8 seconds. Test the accuracy of this account. (Suggestion: Find p(rho) in Equation 4 by assuming a terminal velocity of 100mph. Then calculate the time required to fall 1200 ft.)

And Equation 4: dv/dt= -pv-g where p= the greek symbol rho.

I'm trying to solve this question as a review for my upcoming exam, but I'm not sure how to do this or approach this question. Please show step by step and explain. Thank you.
