A Tesla Model S Performance car has two motors, with a combined output power of 568 kW. The car is able to accelerate from rest to 100 km/h within 2.6 seconds. The mass of the car is 2240 kg. Ignore air resistance, calculate:

(a) the kinetic energy of the car at 100km/h,

(b) the total energy consumption of the motor during the acceleration process,

(c) the energy efficiency of the Tesla car during its acceleration process
