Answer
a) 88 ft/s
b) $9.8 m/s^{2}$
c) $1000 kg/m^{3}$
Work Step by Step
100cm=1m and 1000g=1kg
a) (60 mi/h)($\frac{1h}{3600s})(\frac{5280ft}{1 mi}$)= 88ft/s
b) $(32 ft/s^{2})(\frac{30.48cm}{1ft})(\frac{1m}{100cm})= 9.8m/s^{2}$
c) $(1.0g/cm^{3})(\frac{100cm}{1m})^{3}(\frac{1kg}{1000g})= 1000kg/m^{3}$
