1.59x10^5km/h^2=( )km/h·s 1.59x10^5km/h^2=( )m/s^2 41mile/h=( )ft/s 41mile/h=( )m/s
拜托了~~~~~~~~~~~各位.

1.59x10^5 km/h^2
= 1.59x10^5 km/(h·3600s)
= (159000/3600) km/h·s
= 44.167 km/h·s
1.59x10^5 km/h^2
= 1.59x10^5 x 1000m/(3600s^2)
= (1.59x10^8 / 3600) m/s^2
= 4.4167x10^4 m/s^2
余类推.
再问：还有三道。。。
再答： 41mile/h = 41 x 5280 ft/(3600s) = (41 x 5280 / 3600) ft/s = 60.13 ft/s 41mile/h = 41 x 1609m/(3600s) = (41 x 1609 / 3600) m/s = 18.32 m/s

问几道物理计算题7X10的平方M\s= km\h7.2X1的5平方km\h= m\s360m\min= cm\s 2Km/h=___m/s 36km/h=__m/s 20m/s=__km/h 10m/s=__km/h 216km/h= 如5km/min= km/h= m/h= km/s= m/s km/h=?m/s? 2m/s=( )km/h,54km/h=( )m/s 5m/s=多少Km/h 1m/S=3.6km/h ,那么5m/s=?km/h (1)1km/h= km/min =m/s (2)8m/s= m/min =km/s 1km/min=?km/h=?m/h=?km/s= m/s 1km/h=多少km/s （1）20m/s=______km/h；（2）108km/h=______m/s 1km/h=?m/s
