0.075 kg sphere is held at rest within a fluid. At t = 0, the mass is released and falls straight down, through the fluid. The fluid exerts a resistive force on the object that is proportinal to the object's speed. The terminal speed of the mass is found to be 2.50 m/s. a) What is the time constant of the system? b) After being released, how long does it take the mass to achieve a speed of 1.50 m/s? c) What resistive force acts on the mass at a time of 0.500s?

You are part of a team in an engineering class that is working on a scale model of a new design for a life vest. You have been asked to find the mass of a piece of foam that will be used for flotation. Because the piece is too bulky to fit on your balance, you break it into two parts. You measure the mass of the first part as 128.3 0.3 g and the second part as 77.0 0.3 g. a. What are the maximum and minimum values for the total mass you might reasonably report? b. What is the best estimate for the total mass of the foam? Hint: Propagation of uncertainty is described in Appendix A.
A person of mass m stands on a rope ladder that is hanging from a freely floating balloon of mass M. The balloon is initially at rest with respect to the ground. (The buoyant force on the personballoon system is countering the force of gravity.) a. In what direction will the balloon move if the person starts to climb the rope ladder at constant velocity v relative to the ladder? b. At what speed will the balloon move if the person starts to climb the rope ladder at constant velocity v relative to the ladder?
An inflated spherical beach ball with a radius of 0.3573 m and average density of 10.65 kg/m3 is being held under water in a pool by Janelle. The density of the water in the pool is 1000.0 kg/m3. When Janelle releases the ball, it begins to rise to the surface. If the drag coefficient of the ball in the water is 0.470 and the constant upward force on the ball is 1875 N, what will be the terminal speed of the ball as it rises? Ignore the effects of gravity on the ball.
