A shuffleboard disk is accelerated at a constant rate from rest to a speed of 4.2 m/s over a 1.4 m distance by a player using a cue. At this point the disk loses contact with the cue and slows at a constant rate of 2.7 m/s2 until it stops. (a) How much time elapses from when the disk begins to accelerate until it stops? (b) What total distance does the disk travel? I dont even know where to begin on this one, Please give me any hints, concept or formula's to begin with. Thanks in advance.
