The following conversions occur frequently in physics and are very useful. (a) Use 1 mi = 5280 ft and 1 h= 3600 s to convert 60 mph to units of ft/s. (b) The acceleration of a freely falling object is 32 ft/s?. Use 1 ft = 30.48 cm to express this acceleration in units of m/s?. (c) The density of water is 1.0 g/cm³. Convert this density to units of kg/m³. %3D
