On a sunny day, a distracted driver on his cellphone noticed a tree way too late. He screeches as he slowed down but still hit the tree at 20 km/h. Afterwards, it was measured that he left a tire mark of 6.0 m in length (tire marks for only front tires drawn above). a) Calculate the car’s speed, in km/h, before the driver started slowing down. Define a system, draw energy state diagrams, and include a FBD for any forces. b) If this happened on an uphill slope of 6°, what would have been the car’s initial speed in km/h?
