1. The problem statement, all variables and given/known data A car is hauling an 88 kg trailer, to which it is connected by a spring. The spring constant is 2350 N/m. The car accelerates with an acceleration of 0.29 m/s^2. By how much does the spring stretch? 2. Relevant equations Fx -kx 3. The attempt at a solution Fx -kx 88(.29) = -2350x x = -0.01085957 This seems right. I tried -.0109 and .-01086 but no luck with that either. Am I using the wrong formula?
