Aplayer uses a hockey stick to push a puck at a constant velocity across the ice. the weight of the puck is 1.70 n. the coefficient of friction is 0.0600. with what force must the player push the puck so that his force just equals the frictional force?

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.
