A spring stretches 0.150 m when a 0.300 kg mass is suspended from it. The spring is then pulled down an additional length of 0.10 m and is released. Determine (a) the spring constant, (b) the amplitude, (c) the maximum speed, (d) the maximum acceleration (magnitude), (e) the speed when the mass is 0.050 m from the equilibrium position, (f) the period
