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/s2.
(c) The density of water is 1.0 g/cm3.Convert this density to units of kg/m3.
