If themass is changed to m' = m/2, and the spring force is changed to k' = 2k, then the new frequencyf' ofthe oscillation would be,(a) f' = 2f(b)f' = f(c) f' = f/2(d)f' = 4fThe following given is for questions 3 and 4:A block of mass m = 2 kg is attached to a spring with spring constant k = 200 N/m, and set tooscillates on a frictionless horizontal surface. At time t = 0 its position is xo = 0 and its velocity isvo = +5 m/s.3) Which of the following is true about the oscillation amplitude and the phase constant, :(a) A = 0.5, p =n/2(b)A = 0.5, ø=-1/2(с) А %3D 0.25, ф -л/2(d)A = 0.25, 9=-n/24) When the block's velocity has the value v = max/2, then its position has the possible values of:(а)х %3D +(3/4)A(b)x = ±A/2(c) x = ±(v3/2)A(d)x = ±(v2/2)A5) A block-spring system oscillates in a simple harmonic motion on a frictionless horizontal table. Itsdisplacement varies with time according to x(t) = 0.2 cos(2t – 1/4). The earliest time the particlereaches position x = 0.1 m is(a) t =S24(b) t =2447T(c) t =24(d) t =126) Consider a bob attached to a vertical string. At t = 0, the bob is displaced to a new position where thestring makes -8° with the vertical and is then released from rest. If the angular displacement 0(t) iswritten as a cosine function, then the phase constant o is:
