An object moving in a liquid experiences a linear drag force: B = (bv, direction opposite the motion), where b is a constant called the drag coefficient. For a sphere of radius R, the drag constant can be computed as b = = 67mR, where n is the viscosity of the liquid. Find an algebraic expression for v, (x), the x-component of velocity as a function of distance traveled, for a spherical particle of radius R and mass m that is shot horizontally with initial speed vo through a liquid of viscosity n. Water at 20C has viscosity n = 1.0 10- N s/m. Suppose a 1.0-cm-diameter, 1.0 g marble is shot horizontally into a tank of 20C water at 10 cm/s. How far will it travel before stopping?
