1. The problem statement, all variables and given/known data A 1.54 m wide, 1.48 m high, 1600 kg car hits a very slick patch of ice while going 19.0 m/s. Air resistance is not negligible. If friction is neglected, how long will it take until the car's speed drops to 12.0 m/s? To 11.0 m/s? 2. Relevant equations Kinematics equations, F=ma 3. solution I have no idea how to solve this :-( If you solve it, please explain WHY?
