Consider two cars, a 700kg Porsche and a 600kg Honda Civic. The Porsche is speeding along at 40 m/s (mph) and the Civic is going half the speed at 20 m/s.

A popular web video shows a jet airplane, a car, and a motorcycle racing from rest along a runway . Initially the motorcycle takes the lead, but then the jet takes the lead, and finally the car blows past the motorcycle. Here let’s focus on the car and motorcycle and assign some reasonable values to the motion. The motorcycle first takes the lead because its (constant) acceleration am = 8.40 m/s2 is greater than the car’s (constant) acceleration ac = 5.60 m/s2, but it soon loses to the car because it reaches its greatest speed vm = 58.8 m/s before the car reaches its greatest speed vc= 106 m/s. How long does the car take to reach the motorcycle?
