In the first image, the diagram shows a cart with a spring colliding with the fixed bracket on the track at three different instant during a collision. t1 is shortly after collision with the bracket, t2 is at maximum compression of the spring, and t3 is after the spring has recovered most but not all of its normal length. a. On the second picture, indicate possible times t1, t2, and t3 on the time axis of the force-time graph. Determine approximate values of of the force at each of those instants. b. If the mass of the cart and sensor is 0.850 kg, calculate the acceleration at each instant. c. Draw the velocity and acceleration vectors above the cart at each instant t1, t2, and t3 and make sure that their relative lengths are appropriate. Explain how your response would have been different if the bumper had been made of clay.
