Immediately after the golf ball is hit by the putter, the ball has 12 joules of mechanical energy. Seconds later, after the ball has rolled several meters through the grass, its mechanical energy has dropped to 4 joules due to friction with the grass and air.
The amount of mechanical energy lost by the golf ball is the amount of heat energy gained by the ball, grass, and air molecules due to friction.

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.
