Time to be a crash investigator! two cars are in an accident: car a was driving due east when car b, driving due north, ran a stop sign and collided with his car, causing an inelastic collision (the cars stuck together). the skid marks from the accident go off at a 66 degree angle above the horizontal (east). a traffic camera witnessed car a going 30 mph prior to the crash, and both cars traveling 29.5 mph after the crash. unfortunately, the camera was angled so it did not see car b prior to the crash.
car a has a mass of 1000 kg, and car b has a mass of 1500 kg.
the driver of car b claims that he was driving the 30 mph speed limit, and didn’t see the stop sign because of foggy weather. driver a claims driver b was speeding and that is why he missed the stop sign.
how fast was car b traveling prior to the crash?
