OP warned about not using the homework template
The problem seems very straight forward, however it's proving stubborn. The problem is as follows: We have a mass of 25kg sliding on a table with a frictional coefficient of 0.36. What is the frictional force in Newtons? Now, I know the force of friction to be Fƒ = μmg and also Fƒ = μmg⋅cosα, but the angle in this case is 90 degrees, so I immediately ruled the second equation out. To me, this should be Fƒ = (0.36)(25kg)(9.81) = 88.29 Newtons of frictional force, but that apparently is incorrect. Any input on what I may be doing wrong, but may not understand about this process in general?
