A 7.2-kg mass oscillates on a horizontal spring.The position of the object is given by the relation (all units in MKS).The system is then submerged into a vat of oil with a damping constant of 1.42 kg/s.How long will it take before the amplitude of oscillations becomes 0.314 m?
A)1.01 s
B)10.1 s
C)11.7 s
D)23.4 s
E)The system does not oscillate,it is either over-damped or critically damped.
