Question: A 4-kg collar can slide on a frictionless horizontal rod and is attached to a spring of constant k. It is acted upon by a

A 4-kg collar can slide on a frictionless horizontal rod and is attached to a spring of constant k. It is acted upon by a periodic force of magnitude P = Pm sin, ωft where 9 Pm = N and 5 ωf = rad/s. Determine the value of the spring constant k knowing that the motion of the collar has an amplitude of 150 mm and is

(a) In phase with the applied force,

(b) Out of phase with the applied force.

P = P, sin ayt
