Question

elear My Mi PAU Stat A block Mi, resting on a horizontal track, is connected to a string that passes over a frictionless pulley and then is fastened to a hanging object M2 as shown in the graplh Both masses are released released from it is converted to kinetic energy of Mi and M2 and heat (work) used to overcome the friction between Mi and the track. Show how you can usc x (the initial position of Mi), xf (the final position of Mi), and t (the time that takes Mi to move from xi to xr) to determine the coefficient of friction between Mi and the track from rest. As M2 falls down, the gravitational potential energy f 9 questions ved ge 1: The followings are the measurements from one group of students M1-128.41 g, M2-50.20 g, Xi-33.30 cm, xf-87.80 cm, At = 1.48 sec, what should be their μk value?
