1) In a horizontal block-spring system m = 0.3 kg and k = 5 N/m. At t = 0.1 s, the
velocity is v = -0.15 m/s and the acceleration a = +0.85 m/s^2. Find: [4p]
(a) An expression for the displacement as a function of time, x(t).
(b) The times in the first cycle when IvI = 0.5Vmax, where Vmax is the maximum
speed
