How fast was the drunk going just before the collision

Reference no: EM13546097

A drunk driver in a 2300kg car plows into a 2100kg parked car with its brake set. Police measurements show that the two cars skid together a distance of 20m before stopping. If the effective coefficient of friction is 0.68, how fast was the drunk going just before the collision?
