Alarge sport utility vehicle has a mass of 2700 kg. calculate the mass of co2 emitted into the atmosphere upon accelerating the suv from 0.0 mph to 67.0 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.)
