Evaluate and express the following in SI units hacing an appropritate

a) 354mg(45km)/(0.035 6kN)

b) (0.004 53M)(201ms)

c) 435MN/(23.2mm)

d) (0.0631 Mm)/(8.60 kg)2

e) (35mm)2 (48kg)3

Solution:

a) =0.354g(45m)/(0.0356N)  = 447.47(g*m/N)= 0.447(kg*m/N)

b) = 4530/(0.201s) = 22537 (s-1)

c)= 4.35*10^8 N/(0.0232 m) = 187.5(N/m)

d) = 6.31*10^4 m/(8.6 kg)2 = 853.1 m/kg2

e) = (3.5*10^-2 m)^2/(48kg)3 = 1.1*10^-8 m/kg3
