A 1202-kg car is stopped at a stoplight. Inside, the car has three occupants. The two passengers have a mass of 75 kg each, while the driver has a mass of 105 kg. The driver steps on the gas pedal, and the car begins to accelerate at a rate of 2.5 m/s2 . What is the force that the engine is applying to the car?

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
