How fast was the drunk going just before the collision

Reference no: EM13270437

A drunk driver in a 1700 kg car plows into a 1300 kg parked car with its brake set. Police measurements show that the two cars skid together a distance of 20 m before stopping. If the effective coefficient of friction is 0.77, how fast was the drunk going just before the collision?
