Physics

Two cars are moving at 60 mph in the same direction and in thesame lane. The cars are separated by one car length (20 ft) foreach 10 mph. The coefficient of friction (skidding) between thetires and the roadway is 0.6. The reaction time is assumed to be0.5 sec. a) If the lead car hits a parked truck, what is the speedof the second car when it hits the first (stationary) car? b) Ifthe lead car hits a parked truck and comes to an abrupt halt, atwhat speed does the rule of one car length of spacing for every 10mph of speed become unsafe? c) At 60 mph, what should the ruleactually be?
