//Given Data:-
V=18; //Absolute Velocity of the Jet, m/s
a=0.04; //cross-sectional area of Jet, m^2
u=28; //Speed of the ship, km/hr
//Data Used:-
rho=1000; //Density of water, kg/m^3
//Computations:-
u=u*1000/3600; //m/s
//(a)
F=rho*V*a*(V+u); //N
//(b)
eta=2*u/(V+2*u)*100; //In percentage
//Results:-
printf("(a)Propelling Force, F=%.f N \n", F)
printf("(b)The Efficiency of propulsion, eta=%.2f percent \n", eta) //The answer vary due to round off error
