Question
A box, placed on an inclined plane does not slide. A slight push, however, causes the box to slide down the plane at an increasing speed. Which of the following equations shows why the box is in an unstable equilibrium?
a. Fnet = 0
To solve the problem, you must write a clear and convincing justification for accepting one of the possible answer choices as the best or most appropriate and for rejecting each of the other choices as less appropriate. Your reasons for rejecting choices are just as important as your reasons for choosing the best answer.
Explanation / Answer
As the coefficient of static friction is greater than coefficient of kinetic friction.
When the box is at rest on the inclined plane the gravitational force on the box along the inclined plane is less than limmittin friction.So box does not slide on the inclined plane,after pushing it tends to motion then the friction is kinetic.Now the speed of the block increases.
The option d is best relation to understand the sotuation.
So option d is the correct answer.
