Extracted text: 3. A car travelling at 130 kph locks up its wheel and skids up 3% incline before crashing into a stationary massive concrete pedestal and coming to a complete stop. The skid marks leading up to the pedestal are 90m long. The coefficient of friction between the tires and the road is 0.35. a.) How far would the car have skidded if it had not hit the pedestal? b.) What was the speed of the car at impact ?
