Ok, here is the question, which I thought was easy at first but...
A block whose weight is 45.0N rests on a horizontal table. A horizontal force of 36.0N is applied to the block. The coefficients of the static and kinetic friction are 0.650 abd 0.420 respectively. Will the block move under the influence of the force and if so what wiil be the block's acceleration?
(u=the coefficient)
I used the fs=us(Fn)= .650(45.0N)= 29.3N
fk=uk(Fn)= .420(45.0)N= 18.9N
I know that this will make the box move, but I am a little confused on where to go from here. Do I use F=MA?
Thanks!
