Item 8 An 14000 kg freight car rests against a spring bumper at the end of a railroad track. The spring has constant k = 3.2 x 105 N/m. The car is hit by a second car of 8600 kg mass moving at 9.5 m/s, and the two couple together. Part A Find the maximum compression of the spring. Express your answer using two significant figures. |Tmax| = Submit Request Answer Part B Find the speed of the two cars when they rebound together from the spring. Express your answer using two significant figures. v = m/s Submit Request Answer Provide Feedback
