What speed should be used to make the distance from the starting point to the first obstacle, so that the ball is not too fast and the ball is not too slow to delay? This distance is difficult for me to control.
Is the obstacle around the pole in the regular senior high school entrance examination an ice cream cone or a 2-meter-high pole?
I have a lot of questions. I hope the patient prawn can help me.
Your help will be my salvation/my future.
