Analysis: In the process of skipping rope, the ascending stage is to overcome gravity and the descending stage is the process of gravity. Getting information from the problem can solve this problem.

(1) Read the time t for jumping once from the diagram and calculate the number of jumps n within 1min; Read the time of a stop from the map, and you can find the time of * * * within 1 minute.

(2) The gravity G of the object can be calculated by using the gravity formula, the maximum height H of take-off can be known from the figure, and the work W done to overcome gravity can be calculated by using the work calculation formula;

(3) According to the definition of power, the average power p can be estimated.
