You are a traffic accident investigator. you have arrived at the scene of an accident.
two cars of equal mass (1,000 kg each) were involved in a rear-end accident at a stop sign.
here is what you know: car 1 approached the intersection from the top of a 25-meter hill. car 2 was on a flat stretch of road directly in front of car 1.
at the bottom of the hill, car 1 was going 20 m/s; car 2 was going 30 m/s before it stopped at the stop sign. there were no skid marks left by car 2. the collision occurred at the stop sign, where car 2 had stopped.
after the collision, both cars were moving together in the same direction at 10 m/s before slowly rolling to a stop.
you must now push car 2, using 800 n of force, 10 meters off to the side of the road so no one else gets hurt.
