3. A 0.400 kg object is released from rest while immersed within a fluid. The object is subject to 2 forces while it descends within the fluid: 1. The force due to gravity and 2. A resistive force having a magnitude of by where b is a constant and v is the speed of the mass. a) If the time constant of the system is 0.670 s, what is the constant, b, equal to? (T => 0.6706 0.400 b b=0.400 10.597 kls OCTOS Vy = mg b. What is the terminal speed of the mass? 3109.8) b 0.592 149.25 mis こて
