In a physics lab, students are asked to predict how the acceleration of the block sliding up a ramp compares to the acceleration down the ramp compares to the acceleration down the ramp. The block slides up a somewhat rough surface inclined at an angle of theta above the horizontal. The mass slows down and comes to rest for an instant, and then slides back down the incline. So my question is the acceleration up and down the same or is one greater than the other?
Please explain how these equations apply to each of the 3 assumptions: (same, greater, lesser)
1) a=Fnet/m
2) a=delta t/t
3) Ff=muFn
4) Fg=mg
5) W=Fd
6) Ei+Wnc=Ef
Thank you so much!!
