To graph:We have to sketch a graph representing the situation as height of object versus time and label each section when we throw a disc into the wind, it hits a tree branch and lands on a roof. After staying there for a minute, it comes back to the ground.

Explanation of Solution
Given Information We throw a disc into the wind, it hits a tree branch and lands on a roof. After staying there for a minute it comes back to the ground.
Graph
Interpretation Initially, when the disc is thrown, it is at some height, then it flies in the air for a few seconds before hitting the tree, we can see the graph ascending till it reaches the highest point. After hitting the tree, it reaches the roof, so the graph is descending, and then becomes parallel to the x-axis as it is in rest for one minute. Then, wind blows it to the ground, so the graph is again descending till it meets x-axis again in a few seconds.
