Case Between Two Passing Cars
Hey there! I was hoping to get some help on this question, im not quite sure what im suppose to do! :(
Question: Consider the problem of the passing of one car by another. Assume that one car is moving at constant velocity, and the second car, the passer, has an initial velocity less then that of the other car. Assume that the power (P) of the passer is fixed, and therefore the (maximum) force applied by the engine is P/|Vpasser| (why?). What are the motions of the cars?
Im not exactly sure what this question wants me to do! help would be much appreciated! :)

Hey TszHin! Welcome to PF!
so the acceleration won't be constant … so what will the graph look like?
(and power = energy per time = force x distance per time = force x speed)
