Step 1
Given that the radius \( r = 2 \times 10^{-3} \) m, we have: \( V = \frac{4}{3} \times \pi \times (2 \times 10^{-3})^3 \). Show more…

A steel ball of diameter $3.2 \mathrm{~mm}$ falls under gravity through an oil of density $920 \mathrm{~kg} \mathrm{~m}^{-3}$ and viscosity $1.64 \mathrm{Ns} \mathrm{m}^{-2}$. The density of steel. may be taken as $7820 \mathrm{~kg} \mathrm{~m}^{-3}$. What is the terminal velocity of the ball ? (A) $3.45 \mathrm{cms}^{-1}$ (B) $4.25 \mathrm{cms}^{-1}$ (C) $1.85 \mathrm{~cm}^{-1}$ (D) $2.39 \mathrm{cms}^{-1}$
Using the equation of the previous problem, find the viscosity of motor oil in which a steel ball of radius 0.8 mm falls with a terminal speed of 4.32 cm/s. The densities of the ball and the oil are 7.86 and 0.88 g/mL, respectively.
What is the terminal speed of a 6.00 kg spherical ball that has a radius of 3.00 $\mathrm{cm}$ and a drag coefficient of 1.60$?$ The density of the air through which the ball falls is 1.20 $\mathrm{kg} / \mathrm{m}^{3} .$
