A block attached to a horizontal ideal spring oscillates with amplitude 0.10m and time period 0.50s. At t=0, it passes through the equilibrium position moving towards the positive extreme. Determine the displacement x, velocity v, and acceleration a of the block at t=0.125s.
a) x=0.10m,v=0m/s,a=+15.8m/s2
b) x=0.10m,v=0m/s,a=−15.8m/s2
c) x=0m,v=1.26m/s,a=0
d) x=0.05m,v=1.26m/s,a=−7.9m/s2
