A nonlinear spring is used to launch a toy car. The car is pushed against the spring, compressing the spring 2.5 cm The force the spring exerts on the car is given by the equation F=-Ka?, where K = 5000 The potential energy stored in the spring when the car is pushed against it is most nearly A 0.026J B 1.6J с 3.2J D 125J E 26,000J
