===== Example: Gravitational force and Kinematic equations on the Moon =====



=== Video ====
Part 1:

The diagram to the right (in the video) represents the motion of a rock launched from the surface of the moon. The rock is 2 kg, reaches a maximum height of 5 m, and is launched at an angle of 30 degrees.

a) Calculate 'g' on the moon.
