A block sliding down a fixed inclined plane slows to a stop. Which of the following is true?
A) A change in the normal force caused the block to stop.
B) The kinetic friction force was less than the component of the weight down the inclined plane.
C) The kinetic friction force was greater than the component of the weight down the inclined plane.
D) The static friction force overcame the kinetic friction force.
Homework Answers
the downward motion of the crate is being balanced by kinetic fricitonal force, it means kinetic fricitonal force must be greater than downward acceleration in order to bring it in rest state.
so option (c) is correct
