A fully charged battery supplies power to an electric car of mass 2900 kg. Determine the amount of energy depleted from the battery as the car accelerates from 0 to 140 km/h

Solution

v is equal to 140 km/hr --- 38.89 m/s

so kinetic energy is equal to 0.5mv^2 so it is equal to 0.5*2900*(38.89)^2 which is equal to 2193026.545 joule.

so the battery supplies this energy.
