The kentucky derby, the first of three horse races for the triple crown, was won on may 7, 2000 by fusaichi pegasus with a time of 121.3s. if the race covers 2011.25m, what is the horses's average speed?

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?
