PLEASE HELP ME two cars, an accord and a camry, face eachother. they are initially 150 m apart. the accord starts out with a velocity of 10.0 m/s and increases its velocity at a rate of 2.00 m/s^2. the camry, however, starts out with a velocity of 5.00 m/s and increases its velocity at twice the rate of the accord. at what time do the two cars crash and burn?

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?
