Hello,
I have a problem that I am stuck with. The problem consists of a 2.60kg box sliding across the horizontal floor of an elevator. The coefficient of kinetic friction between the floor and the box is 0.490. I have to determine the kinetic frictional forces of different cases.
(a) when the elevator is stationary ------Which I have already done. That part was easy.
but I'm stuck on the following two.
(b) when the elevator is accelerating upward with an acceleration of 1.30 m/s^2
(c) when the elevator is accelerating downward with an acceleration of 1.30 m/s^2.
I assumed that I could use the equation, kinetic frictional force = kinetic friction times mass and acceleration. That however was not correct.
Any help or direction provided would be greatly appreciated.
