Do you have any idea about the free body diagram of a basketball player?

Question

a) just before leaving the ground on a jump

b) b) while in the air

may i know wat are the forces acting on the player exept for the normal for and gravity? thanks!

Answer 1

there are two answers two your question part A

in basketball there are two shots in which player gets airborne

first one is Jump Shot in this only vertical jump is there

let me show u how

a)                                   A  normal                                  

                                      |                                  

                                      |

               ----------------- player--------------------ground

                                      |

                                      |

                                      v pushes the ground (mg+F ) where F is the force applied

b) This case called lay up where there are two forces applied by the player first one is due to kinetic energy and second one due to force

a)              normal           A         resultant force                          

                                      |     /                              

                                      |    /45*

              ground ---------- player---------------->KE=1/2mv^2 where v is

                                      |                          the speed of the player

                                      |

                                      |

                                      v pushes the ground (mg+F ) where F is the force applied

b)

while in the air

             normal              A        Force                          

                                      |                                  

                                    player  

              ground --------------------------

                                      |            

                                      |

                                      |

                                      v gravitational force

Answer 2

For the first one its only the normal and gravity.

For the second one its normal, gravity, air friction, and the force the player exerted upward with his legs.
