= SOLUTION 0 .5 v θ = m /s, and 0 r v = . Neglecting the mass of the rod and the effect of friction, determine the radial and transverse components of the velocity of the collar when 120 r = mm . PROBLEM 13.95 A 2.5 kg collar A is attached to a spring of constant 7 50 N / m and undeformed length 150 mm . The spring is attached to point O
