Question
**1. Mr. Mangan throws a rock with an initial velocity of 50 m/s at an angle of 30 degrees above the ground. How far does the rock go?**

Some handwritten equations can also be observed on the image:
\[ d = v_i t + \frac{1}{2} a t^2 \]

Where \( d \) is displacement, \( v_i \) is initial velocity, \( t \) is time, and \( a \) is acceleration.

And another equation:
\[ d = 0 (2.5) + \frac{1}{2} (9.8)(7.8)^2 \]

It seems like an attempt to solve for the displacement of the rock using kinematic equations.

Note: There are no graphs or diagrams in the image.
