If body A is sliding over B due to an accelerating force, then A will have a constant velocity when
A. Kinetic friction equals the accelerating force
B. Equilibrium does not exist
C. Static friction equals the accelerationg force
D. the normal force equals zero
Accelerating force?
A.
At that point the net force acting on body A is zero.

Reply:A. Kinetic friction equals the accelerating force in magnitude and opposite in direction.
Reply:A! Chea chea!
