# The following conversions occur frequently in physics and are very usefnl. (a) Use I mi = 5280 ft and I h = 3600 s to con-vert 60 mph to units of fils. (b) The acceleration of a freely falling object is 32 fi/s2. Use 1 ft = 30.48 cm to express this acceleration in units of rn/s2• (c) The density of water is 1.0 g/cm'. Convert this density to units of kg/m'.?

Please perform units conversions for me. Thank you :)
