An electric car has a maximum speed of 270 km/h. It accelerates from rest with a constant acceleration of 2.5 m/s2.
(i) Define acceleration.
(ii) Show that the maximum speed of the car is 75 m/s.
(iii) Calculate the time taken for the car to reach its maximum speed.
(i) The car has a total mass of 2200 kg. Calculate the horizontal force which causes the acceleration of the car.
(ii) The car travels into a headwind. The force of this headwind opposes the motion of the car. State and explain the effect of this force on the acceleration of the car, assuming the car's engine continues to provide the same driving force.
