Throwing with the wind, a quarterback passes a football 140 ft in 2 s. against the wind, the same pass would have traveled 80 ft in 2 s. find the rate of the pass and the rate of the wind.

When we throw the ball along the direction of the wind then the net speed of the ball is sum of speed of ball and speed of wind.

Now when wind is blowing opposite to the direction of the ball then net speed is subtraction of ball speed and wind speed

Now if we subtract above two equations

so wind speed will be 15 ft/s

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
