An astronaut stands on the surface of a spherical asteroid that has a weak gravitational field but no atmosphere. The astronaut throws a small rock straight upward, as shown at left above. The rock travels upward until it reaches a distance of 2R from the center of the asteroid, where R is the asteroid’s radius, and then falls back down to the asteroid’s surface.
The dots below represent the rock immediately after being thrown and when it is a distance 2R from the asteroid’s center. On each dot, draw and label the forces (not components) exerted on the rock at the indicated time. Each force must be represented by a distinct arrow starting on and pointing away from the appropriate dot.
Note: Draw the relative lengths of all vectors to reflect the relative magnitudes of all the forces at both times.
Please explain how to get the vectors, thank you
