According to one model that takes into account air resistance, the acceleration a(t) in m/s^2 of a skydiver of mass m in free fall satisfies a(t) = -9.8 + u(t)^2, where u(t) is velocity, negative since the object is falling, and k is a constant. Suppose that m = 60 kg and k = 13 kg/m.
What is the object's velocity when a(t) = -2.9?
Use decimal notation. Give your answer to two decimal places.
v(t) =
m/s

What is the object's velocity when a(t) = 0? This velocity is the object's terminal velocity.
Use decimal notation. Give your answer to two decimal places.
