(a) A sphere made of plastic has a density of 1.08 g/cm^3 and a radius of 7.50 cm. It falls through air of density 1.20 kg/m^3 and has a drag coefficient of 0.500. What is its terminal speed (in m/s)?

(b) From what height (in m) would the sphere have to be dropped to reach this speed if it fell without air resistance?
