Problem Set 1 Problem 1 Convert the following to the SI Unit

Problem Set 1 Problem 1. Convert the following to the SI Units indicated a. 122 mph to m/s b. 161 ft/s^2 to m/s^2 c. 6666 in^2 to m^2 d. 21 furlong/ fortnight to mm/s e. 307 psi to Mpa

Solution

a) 1mph = 0.44704 m / s
so, 122mph = 54.54 m/s

b) 1ft/s^2 = 0.3048 m / s2
=> 161 ft/s^2 = 49.073 m/s^2

c) 6666in^2 =4.301 m^2

d) 21*201168/1209600 = 3.4925 mm/s

e) 307*0.00689476 =2.12 Mpa

f)55*0.0146/0.0283168 = 28.36 Mg/m^3
