Astronauts on a distant planet throw a rock straight upward and record its motion with a video camera. After digitizing their video, they are able to produce the graph of height, y, versus time, t, shown in Figure 2-36. (a) What is the acceleration of gravity on this planet? (b) What was the initial speed of the rock?

Step 1 of 4
In this problem, for an Astronauts on a distant planet, throws a rock straight in upwards direction, we need to find, (a) the acceleration of gravity of planet and (b) the initial speed of the rock.
