A large sport utility vehicle has a mass of 2500kg. Calculate the mass of CO2 emitted into the atmosphere upon accelerating the SUVfrom 0.0mph to 66.0 mph. Assume that the required energy comes from the combustion of octane with 30% efficiency. (Hint: Use KE= 1/2mv^2 to calculate the kinetic energy required for the acceleration.) I already converted mph to m/s by multiplying by .44704. and got 28.1635m/s. then I you have the used this equation Work=.5*2500*(28.1635)^2-.5*2500*0^2....but whats next?
