Question

Part A The collar A, having a mass of 0.75 kg is attached to a spring having a stiffness of k = 300 N/m. When rod BC rotates about the vertical axis, the collar slides outward along the smooth rod DE The spring is unstretched when s 0. Neglect the size of the collar. (Figure 1) Determine the constant speed of the collar in order that s 100 mm, Express your answer to three significant figures and include the appropriate units. li Value Units Figure 1 of 1 Submit Request Answer Part B What is the maqnitude of the normal force of the rod on the collar? Express your answer to three significant figures and include the appropriate units. ? Value Units N = Request Answer Submit

Answer 1

=> given: mam (m) = 0.15 kg Shfreno (K) = 300 N/m AY When S: 100 mm m As per Hooke low my²mo KS ks ma Ks = my2 KS? =v2 ie, V- sk K s2 m 300% :12 - 2012 075 lie, Corytant Speed of Collar = 2 m/% B) Normal force of rod on Collar: N=mg -- 0 15x9.8) =7.3575 N. Normal force of uod is 7-3575N.
