Look at the graph. The gradient of the curve initially is delta x/ delta y =(20-10)/(10-0).

SUMMARY
The discussion focuses on evaluating the magnitude of the gravitational field at the surface of a planet using the trajectory of a rock thrown with an initial speed of 16.9 m/s. Participants clarify that the gravitational field can be determined by measuring acceleration from a provided graph, rather than using the gravitational formula g = G*M/R², due to the lack of known mass and radius of the planet. The correct approach involves calculating the second derivative of the position function to find acceleration, and then applying kinematic equations to derive the gravitational acceleration.
