a battery provides energy to an electric car. The electric car has an acceleration of 2.9 m/s² when it moves from rest. 
Combined mass of the car and its driver is 1600 kg. 
(i) calculate the time taken to reach a speed of 28 m/s 
(ii) calculate the force required to produce this acceleration 
(iii) calculate the kinetic energy of the car when it's speed is 28 m/s
