What is the magnitude of the skydiver"s acceleration when the upward force of air resistance has a magnitude that is equal to one-fourth of his weight? 4. [2pt] What is the tension T1 ? 5. [2pt] Two blocks m1 = 9.6 kg and m2 = 4.7 kg are connected by a homogeneous rope that has a mass of mr = 1.01 kg. A constant vertical force, F = 185.6 N , is applied to the upper block. What is the magnitude of the acceleration of the system?
