As part of a safety investigation, two 1500 {\rm kg} cars traveling at20 {\rm m/s} are crashed into dissimilar barriers. Discover the average forces exerted on (a) the car that hits a line of water barrels and takes 1.8 {\rm s} to stop, and (b) the car that hits a concrete barrier and takes 0.3 {\rm s} to stop.
