Hello, I was given the hw question that wanted to know if a basketball player is getting ready to jump, pushing off the ground and accelerating upward, what are the forces acting on the player? I have tried the options many of times but can't figure out where I am wrong. For the most part it can't be too many forces acting on the player.  The multi-choice options were: Weight Tension Force Kinetic Friction Force Normal Force I have chosed Normal Force and Weight as my top two. But somehow i'm still wrong or missing something.
