Consider someone driving down the highway at 70 miles per hour (31.3 m/s). The total mass of the driver and their car (as well as everything else in the car) is 1300kg. A) How much work must friction do to make the car stop? I got −6.37×10^5 J B) A tree suddenly falls on the highway 60m in front of the car, and the driver just barely manages to stop before hitting the tree. What is the magnitude of the force of friction necessary to do the work you calculated in part A just before the car hits the tree?
