Aplayer uses a hockey stick to push a puck at a constant velocity across the ice. the weight of the puck is 170 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? 28.3 n 0.999 n 0.102 n 0.0104 n

The minimum force by which player should hit the puck to move it is 0.102 N.

Explanation:

Weight of the puck = 1.70 N

This weight of the puck is the force acting normal to the surface that is:

N = 1.70 N

The coefficient of friction =

Frictional force =

The minimum force by which player should hit the puck to move it is 0.102 N.

Yes.  That's a nice, simple, intuitive description of the process that
liberates energy in the cores of stars and "H" bombs.

When 2 Hydrogen nuclei combine to form 1 Helium nucleus,
the combined nucleus has about 0.7% less mass than the
Hydrogen nuclei had.  That "missing mass" shows up in the
form of energy leaving the site of the fusion.
Can you say "big boom" ?
