0 2 An engineer tests a car by measuring the time taken for it to travel 1500 m at
a constant speed. When delivering its maximum output power of 35 kW the
time recorded is 28 s.
0 2 . 1 Calculate the magnitude of the resistive force that is acting on the car.
[2 marks]
resistive force = N
0 2 . 2 Identify one way in which the engineer could modify the car so that the time to
cover the test distance is reduced.
