Unformatted text preview: Show your reasoning. (Use buckets and Work.) c) If the blocks mass were doubled, would the block slide twice as far, half as far, or some other distance? Assume it starts from the same altitude. Show your reasoning. 2) A car leaves 10m long skid marks on dry pavement. The coefficient of kinetic friction is 0.8. a) How fast was the car going? Show your reasoning. Does the mass matter? b) If the car were traveling twice as fast as in part A, how long would the skid marks be? Show your reasoning. A B k = 0.4 4.5m v = 0...
