Estimate the terminal speed of a wooden sphere (density 0.700 g/cm3) falling through air if its radius is 3.20 cm and its drag coefficient is 0.470.

The terminal speed of a falling object is dictated by the equation terminal speed = sqrt(2gh/Cd) Where g is the acceleration due to gravity (9.8 m/s^2), h is the object's height, Cd is the object's drag coefficient, and ρ (rho) is the objects's mass density. In our case, the object is a wooden sphere with a mass density of 0.7 g/cm3, a drag coefficient of 0.470, and a radius of 3.2 cm. With this information, we can calculate the terminal speed of the wooden sphere. Terminal speed = sqrt(2 * 9.8 m/s^2 * (3.2 cm / 100 cm/m) / 0.470) Terminal speed = 13.2 m/s
