You decided to take the rope with youand had it hanging vertically from a tree and you found the length of your rope to be 20 m. You take your rope and attach it to a cliff that is 4O m in height. You pull the rope the remaining distance so that you are on the ground with your feet holding onto a tree root. You let go and as you can imagine are moving vertically upwards at a certain speed. What was the height you reached from this new experiment you are conducting? Your mass is still 50 kgs and your k constant is 64 other info from previous questions. The rope is still a spring.

At your max height you collide with a alien space craft that happens to be falling straight down with a speed of 400 m/s having a mass of 300kgs. How fast are yougoing after the inelastic collision? Your mass can be found in number fifteen.
