After the first spring compresses a distance of 27.3 cm, the second spring acts with the first to increase the force as additional compression occurs as shown in the graph. The car comes to rest 49.5 cm after first contacting the two-spring system
This implies that you can pick the point about which to sum the torques to simplify the calculation. Often it is best to pick the point where an unknown force acts, so that the torque due to that force is zero. In this problem the simplest equati
