A 20-kg mass i attached to a spring with stiffness 200 N/m. The mass is displaced. The damping constant for the system is 140 N-sec/m. If the mass is pulled 25 cm to the right of equilibrium and given initial leftward velocity of 1 m/sec, when will it first retum to its equilibrium position? (a) The IVP modeling the problem is given by: OA y"-y-12y=0; y(0)=:Y(0) = -1 OB. O C. O D. 1 y" + 7y + 10y=0; y(0) = y(0) = -1 y-6y-54y=0; y(0)= y(0) = -1 1 y" - 10y +25y=0; y(0) = y(0) = -1 OE. None of the given answers is correct (b) This problem is a case of: OA Overdamped Motion OB. Underdamped or Oscillatory Motion OC. Undamped Motion OD. Critically Damped Motion OE.
