3. You are the design engineer in charge of the crashworthiness of new automobile models. Cars are tested by smashing them into fixed, massive barriers at 45.0 km/h to the left. A new model of mass 1500 kg takes 0.150 s from the time of impact until it is brought to rest. Calculate the average force (magnitude and direction) that is exerted on the car by the barrier?
