A 6000 kg freight car rolls along rails with negligible friction. The car is brought to a rest by a combination of two coiled springs as illustrated in the Figure. After the first spring compresses a distance of 0.3 m, the second spring comes on and increases the force as shown in the graph. The car is brought to rest after 0.5 m by the two spring system.
(a) Look at the graph. What is the work done on the springs?
(b) What was the initial speed of the car?
Now consider this applet, where the two blocks have different masses. Plug the starting values into your formula from Part G, using 5 for mass of the red block and 10 for the magnitude of the acceleration of gravity.
