Uppose one gallon of gasoline produces 1.17×108 j of energy, and this energy is sufficient to operate a car for 18.3 miles. an aspirin tablet has a mass of 319 mg. if the aspirin could be converted completely into thermal energy, how many miles could the car go on a single tablet?

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?
