the coefficient of kinetic friction between the block and inclined plane is 0.28 and angle è = 65°. What is the block's acceleration (magnitude and direction) assuming the following conditions?
(a) It is sliding down the slope.
(b) It has been given an upward shove and is still sliding up the slope.
What is your thinking? I am getting the impression you are just grazing for answers.
