+**Part 2: Finding the energy stored in the spring**
 The most straightforward distance to find is finding the maximum possible distance a harpoon can reach. This will occur when the block is dropped over the greatest distance (from the roof) and launched from the highest elevation (also from the roof). So, let's work with this first.

 **Part 4: Does it clear the wall?**
   - Does the time of fall of the horizontally-launched harpoon depend on the launch speed?
-  - Is this constant force motion? If so, we can use kinematics here. How much time does it take the harpoon to reach the wall? Again, keep in variables.

   - What is the elevation of the harpoon at the time found in the previous step - now, use your known quantities to get a numerical value. Does it clear the wall?
 **Part 5: What is the range/ total horizontal distance of the launched harpoon?**
-  * Use a similar procedure here as you used in part 4 to find the range.
+  - Use a similar procedure here as you used in part 4 to find the range with a slight modification.
-  *
+  - Start with the vertical direction to find the time it takes the harpoon to reach the level of the zombies (hit the zombie).
+  - Use the horizontal direction and the time from the previous step to get the range.
 **Part 6: Amount of ice**
   - This is the non-review part of this problem.
