(a) Determine the constant force necessary to accelerate a car of mass 1000 kg from 0 to 100 km/h in 6 seconds.
(b) Also calculate the work done by the force.
(c) Verify that the work done by the force equals the change in kinetic energy of the car. Neglect friction.
(d) What-if Scenario: What would the work be if the acceleration were achieved in 5 seconds?
