 The report should have the following five sections. Each section must be written by a separate student. The whole report must be in a single Google Colab file and attached from Google Drive into the associated Google Classroom assignment.

+Answer the following questions:
+  - What is the difference between systematic and stochastic error? Which errors in this experiment are systematic and which are stochastic?
+  - Why is $\delta s' > \delta h > \delta s$?
+  - Which velocity is greater, before reaching point A or after leaving A?
+  - Is the impulse positive or negative? Why?
