Q72 There is a minecart in a mine that is 5900 kg. The minecart reaches the end of the track and slams into a spring stopper. The minecart was traveling 1.7 meters/second. The spring stopper gets compressed by 0.08 meters. In this problem assume that there is no damping. Determine the value of k k =___ ___N/m Here is a hint: Solve the differential equation while keeping 'k' as an unknown. The spring's compression corresponds to the maximum displacement. It is convenient to assume that the displacement is zero when the minecart is just touching the spring stopper. How much does the spring compress when a 7700 kg minecart collides with it at the same speed as before?write your answer in the blank below: ________m
