500 gr collar C may slide along pole AB. The spring has an undeformed length of 400.0 mm and a spring constant of 135 Mm. Knowing that the collar is released from rest at A and that h : 800.0 mm d : 600.0 mm 3) determine the speed of collar at B if there is friction between collar and rod with a coefficient of friction of \"K = 0.25 l-ls = 0.35 b) using the results of part 3) determine the speed of collar at B ifthere is no friction between collar and rod. NOTE: You may need: ldEi/cose = |n(1/c050 + tane) Ida/c0528 = tanB
