Problem
A 1.5kg toy car pulls a 0.50kg trailer using a light, inextensible string. The car is propelled forward by an internal battery so that the string exerts a forward tension of 2.0N on the trailer and an equal backward tension on the car. Consider the combined car-plus-trailer as the system. Describe in one or two sentences how these two tensions affect (i) the net external horizontal force on the system and (ii) the horizontal acceleration of the system.
