When an object moves through a fluid, the fluid exerts a viscous force F on the object that tends to slow it down. For a small sphere of radius R, moving slowly with a speed v, the magnitude of the viscous force is given by Stokes, law, F = 6πηRv, where η is the viscosity of the fluid. (a) What is the viscous force on a sphere of radius R = 8.9 x 10-4 m falling through water (η =...
If a single constant force acts on an object that moves on a straight line, the object's velocity is a linear function of time. The equation v=vi + at gives its velocity v as a function of time, where a is its constant acceleration. What if velocity is instead a linear function of position? Assume that as a particular object moves through a resistive medium, its speed decreases as described by the equation v = vi-vx, where k is a...

2. Consider the force F shown in the drawing. This force acts on an object that can move along the F positive or negative x axis, or along the positive or negative y axis. The work done by this force is positive when the displacement of the object is along the axis: (a)-x, -y (b)-x, +y (c) +x, +y circular pat What enabl is above po by the tens energy gravitation axis or along the Section 6 and the...
