Question

g A 4-foot spring is elongated167feet long after a mass weighing 16 pounds is attached to it. The medium throughwhich the mass moves offers a damping force numerically equivalent to92times the instantaneous velocity.(a) Find the equation of motion if the mass is initially released from the equilibrium position with a downwardvelocity of 2 ft/s. (Use the convention that displacements measured below the equilibrium position are positive).(b) What is the velocity of the mass whent

Answer 1

Answer: hello question b is incomplete attached below is the missing question

a) attached below

b) V = 0.336 ft/s

Step-by-step explanation:

Elongation ( Xo) = 16/ 7 feet

mass attached to 4-foot spring = 16 pounds

medium has 9/2 times instanteous velocity

a) Find the equation of motion if the mass is initially released from the equilibrium position with a downward velocity of 2 ft/s

The motion is an underdamped motion because the value of β < Wo

Wo = 3.741 s^-1

attached below is a detailed solution of the question
