1. The problem statement, all variables and given/known data On vacation, your 1300 kg car pulls a 540 kg trailer away from a stop light with an acceleration of 2.00 m/s2. (a) What is the net force exerted by the car on the trailer? (b) What force does the trailer exert on the car? (c) What is the net force acting on the car? 2. Relevant equations Force= mass x accelleration 3. The attempt at a solution I was able to solve for part b by applying the above equation and doing the following: (540)(2.00)=F so F=1080. This answer was correct.. however when applying the same logic to part a) (1300)(2.00)= 2600 ... the answer came out incorrect... im not sure what I am doing wrong? For part c I tried subtracting the force of the trailer from the force of the car to get the net force.. this too was incorrect. I am not sure what I am missing here.. please help?
