A block-spring system is in simple harmonic motion on a frictionless horizontal table. Its displacement varies with time according to x(t) = 0.2cos(5t - Tt/2). The earliest time the particle reaches position x = +0.1 m is: Ot= T/12 sec O t= 5Tt/12 sec O t= 5 t/6 sec Ct%= n/6 sec O t= T/30 sec O t= T/60 sec
