//Power of a locomotive
//refer fig.16.7 (a) and (b)
v=(56*1000)/(60*60) //m/sec
F=5*420/1000 //kN
W=420 //kN
P=F+W*(1/120) //kN
//Power of Locomotive Pw
Pw=P*v //kW (mistake in book)
u=15.556 //m/sec
//Resultant force parallel to the plane R
R=F+W*sind(theta) //kN (Down the plane)
s=((420*(15.556^2))/(2*9.81*5.6)) //m
printf("Power of locomotive=%.4f kW\ns=%.4f m",Pw,s)
//The answers vary due to round off error
