    How Does a Skydiver's Velocity Change with Distance After Parachute Deployment?

    Homework Statement A sky driver reaches his terminal velocity of 373 ms^-1 and deploys his parachute at a height of 1500m, the drag force =bv^2 and weigh can be ignored. Find an expression for velocity as a function of distance traveled from the point the parachute was deployed The Attempt at...
