According to one model that takes into account air resistance, the acceleration a(t) (in m/s²) of a skydiver of mass m in free fall satisfies a(t) = ?9.8 + k/mv(t)² where v(t) is velocity (negative since the object is falling) and k is a constant. Suppose that m = 66kg and k = 17kg/m. What is the object's velocity when a(t) = 0?This velocity is the object's terminal velocity.
