The text in your image appears to include instructions and equations related to analyzing motion under gravity. Here’s a breakdown based on what I can read:

1. Objective: Measure the intensity of gravity $g$ or $g_0$ using two different methods.
2. Equation given:
   $y(t) = -\frac{1}{2} g t^2 + V_0 \sin(\theta) t + y_0$
