According to one model that takes into account air resistance, the acceleration a(t) in m/s of a skydiver of mass m in free fall satisfies a(t) = -9.8+ v(t), where v(t) is velocity, negative since the object is falling, and k is a constant. Suppose that m = 65 kg and k = 17 kg/m. What is the object's velocity when a(t) = -2.3? (Use decimal notation. Give your answer to two decimal places.) v(t) = 5.36 Incorrect 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.) v(t) = 6.12 Incorrect m/s m/s According to one model that takes into account air resistance, the acceleration a(t) in m/s of a skydiver of mass m in free fall satisfies a(t) = -9.8+ v(t), where v(t) is velocity, negative since the object is falling, and k is a constant.
