Neglecting the presence of friction, air drag, and other inefficiencies, how much gasoline is consumed when a 1300 kg automobile accelerates from rest to 80 km/h. Assume the density and enthalpy of gasoline are 680 kg/m3 and 45 MJ/kg respectively. Express your answer in the units of mL. Show all work and use SI units for full credit. Box your final answer (s)

Given that,.

Mass of car is

M = 1300kg

Velocity of car

V = 80km/h = 80 * 1000/3600

V = 22.22m/s

Calculate the kinetic energy of the vehicle as follows:

K. E = ½ MV²

K. E = ½ * 1300 * 22.22²

K. E = 320,987.65 J

Given that,

Enthalpy is 45MJ / kg

h = 45MJ / kg

Then, enthalpy is given as.

Enthalpy = Energy / mass

h = E / m

45 * 10^6 = 320,987.65 / m

m = 320,987.65 / 45 * 10^6

m = 7.133 * 10^-3 kg

m = 7.133 mg

Also, given that, density is 680kg/m³

Density is given as

Density = mass / Volume

ρ = m / v

Then, v = m / ρ

v = 7.133 * 10^-3 / 680

v = 1.049 * 10^-5 m³

We know that

1mL = 10^-6 m³

Therefore,

v = 1.049 * 10^-5 m³ * 1mL / 10^-6m³

v = 10.49 mL
