5.)
Since 1 inch = 0.0254 m
and 1 hour = 60*60 sec = 3600 sec.
So, 500 in/h = (500 inch/h)(0.0254 m/1 inch)(1 hr/3600 sec.)
500 in/h = 0.00353 m/sec.
500 in/h = 3.53*10^3 m/sec.
9.)
Since 1 m = 10^-4 cm
So, 35 m^3 = 35*(10^-4 cm)^3
35 m^3 = 35*10^-12 cm^3
10.)
Since 1 km = 1000 m
and 1 hr = 3600 s
So, 50 m/s^2 = (50 m/s^2)(1 km/1000 m)(3600 s/hr)^2
50 m/s^2 = 648000 km/h^2
50 m/s^2 = 6.48*10^5 km/h
