The 2.3-kg collar is released from rest at A and slides down the inclined fixed rod in the vertical plane. The coefficient of kinetic friction is 0.30. Calculate (a) the velocity v of the collar as it strikes the spring and (b) the maximum deflection x of the spring. 2.3 kg A 0.43 m H=0.30 Answers: (a) v = 53 k = 1.1 kN/m m/s (b) x = mm
