Question: A 2-kg block A slides in a vertical frictionless slot and is connected to a moving support B by means of a spring AB of

A 2-kg block A slides in a vertical frictionless slot and is connected to a moving support B by means of a spring AB of constant k = 117N/m. Knowing that the displacement of the support is δ = δm sin ωft where δm = 100mm and ωf = 5rad/s, determine

(a) The amplitude of the motion of the block,

(b) The amplitude of the fluctuating force exerted by the spring on the block.

B 6= 5, sin e
