The damping constant for the system is 307 N secim. f the mass is pulled 10 cm to the right ot equibnum and given an intial rightward ve ocity of 3 m/sec, what is the maximum displacement trom eqa bnium that t twl attain? he msximum dsplcement ismeters (Type an exact answer, using radicals as needed Enter your answer in the answer box and then click Check Answer 2 Clear A Check AnswerExplanation / Answer
m = 5 kg
k = 315 N/m
total energy = k x^2 / 2 + m v^2/ 2 = k A^2 / 2
(315 x 0.10^2) + (5 x 3^2) = 315 A^2
A = 0.39 m ...Ans
