Question: Al. A mass is given an initial speed vo up an inclined rough ramp. Vo m The time for the mass to come to rest

Al. A mass is given an initial speed vo up an inclined rough ramp. Vo m The time for the mass to come to rest up the ramp is tup. The mass then returns down the ramp in time tdown. If tup = 2. Is, tdown = 3.5s and 0 = 200, what is the coefficient of kinetic friction of the rough ramp? [5 points]
