# A block is attached to a ceiling by a spring ofy(1)force constant k. When pulled down andreleased, the block undergoes simple harmonicmotion. The motion of the block is shown in thetime plot on the right. Which of the followingdescribes the amplitude A and frequency fofthe motion of the block?2t(s)16п24T32п8тA = 2; f= 16 HzA = 2; f= 1/(16m) HzA = 4; f = 1/(8m) HzA = 4; f= 1/(16m) HzWhich of the following equations of motion best describes the motion of the block?y(1) = 2cos(18)y(1) = 2cos(81)y(t) = 4cos(16nt)y(t) = 4cos(t/8)%3D(Scroll down to answer last question) If the mass of the block is 4.14 kg, what is the force constant k of the spring?NumberN/m
