When a falling object experiences air resistance, it will eventually reach terminal velocity and no longer accelerate. This will happen when the force of air resistance Group of answer choices is less than the force of gravity acting on the object. is equal to the object's weight. is greater than the force of gravity acting on the object. approaches zero.

Hot-Air Balloon A hot-air balloon of mass M is descending vertically with downward acceleration of magnitude a. How much mass (ballast) must be thrown out to give the balloon an upward acceleration of magnitude a (same magnitude but opposite direction)? Assume that the upward force from the air (the lift) does not change because of the decrease in mass. (Use any variable or symbol stated above along with the following as necessary: g.)

93. A spherical particle falling at a terminal speed in a liquid must have the gravitational force balanced by the drag force and the buoyant force. The buoyant force is equal to the weight of the displaced fluid, while the drag force is assumed to be given by Stokes Law, ?s=6????.Fs=6πrηv. Show that the terminal speed is given by ?=2?2?9?(?s−?1)v=2R2g9η(ρs−ρ1)R is the radius of the sphere, ?sρs is its density, and ?1ρ1 is the density of the fluid, and ?η
