02. (30p) The figure shows a bead, initially at rest, of mass m = 5.5 grams sliding down a wire, and then back up the wire. Frictional forces do not exist for the path from A to B to C. a. (5p) How high must the height, hA, be if the bead is to have a speed of VB = 210.0 cm/s , at the lowest point, B ? b. (5p) Athc= 15.5 cm, what is the speed , Vc? The wire is horizontal from C to D , but the wire is no longer friction-less. At point C the coefficient of friction becomes, Hk = 0.155. c. (5p) What is the force of kinetic friction, fk , for the wire length between C and D? d. (5p) What is the deceleration, a, of the bead along the distance , XCD? e. (5p) What is the distance, XCD, travelled by the bead sliding to rest between C to D? f. (5p) What is the time, tstop, it took to travel the stopping distance , XCD?
