im still having trouble figuring out how to find the force. I don't get the equation I should use.

so first I would find the normal force which in this case is the mass times gravity. N=mg---> N=(0.3kg)(9.81) = 2.943 then after I get this what do i do next

wait I am still kind of slow on this what's the first thing you should do?

Hi I am having problem with this homework problem dealing with the coefficient of friction. A hockey puck having a mass of 0.3kg is slid across the ice, starting with a speed of 12 m/s and slowing to 11.3 m/s after traveling for 3 sec. What is the coefficient of friction between the puck and...
