document.write( "Question 1152078: I am trying to determine the vehicle speed upon impact. Vehicle A weighs 3,428lbs and Vehicle B weighs 4,269lbs. Vehicle A was moving and Vehicle B was stationary (parked). Vehicle A struck Vehicle B from behind and pushed the car forward a distance of approximately 30-feet on dry asphalt. At what speed (mph) must Vehicle A have been traveling at upon impact in order to push stationary Vehicle B 30-feet forward? \n" ); document.write( "
