Question

Shown below are three scenarios in which a truck is pulling a trailer. For each scenario, rank, from greatest to least the difference between the strength of the force the car exerts on the boat trailer and the strength of the force the boat trailer exerts on the car. All cars are identical but the boat trailers have different loads, so they have different masses. Provide a brief reasoning for your answer to each scenario. ALL INCLINES ARE THE SAME DURING TIME TRAILERS ARE ACCELERATING FROM REST TO FINAL GIVEN SPEEDS CARS MOVING AT CONSTANT VELOCITY

Explanation / Answer

Suppose the force that car exert on boat trailer be the reation= Fc-b = F0 i^

Then the boat trailer according to newtons 3rd law will also exert the same force but in opposite direction

Thus, the force that boat trailer exert on car = Fb-c = Fc-b =F0

DIfference of strength of these two forces are always zero as shown, Fb-c -Fc-b = F0-F0 =0

Difference is zero for all the cases.
