You’re an accident investigator at a scene where a drunk driver in a 2200 kg car has plowed into a 1400 kg parked car with its brake set. You measure skid marks showing that the combined wreckage moved 20 m before stopping, and you determine a frictional coefficient of 0.78. What do you report for the drunk driver’s speed just before the collision?
