Realistically, I would say answer a.Originally Posted by RefujoiA box sits at the top of an unloading ramp. As the ramp is gradually tilted down from horizontal, the box will eventually start to slide down the ramp; the ramp then stops futher tilting and is held at this angle. Considering friction realistically, once the box starts to slide it is most- likely to then:
a) come to rest in a short distance due to the difference between static and kinetic.
b) continue to slide with increasing acceleration
c) Continue to slide at a constant speed because of friction, and the ramp tilt has stopped increasing.
d) Continuesto slide at a speed increasing with constant acceleration.
