A spring stretches 0.150 when a 0.300 kg mass is hung from it. The spring is then stretched horizontally 0.100m from its equlibirum point and released. Determine
a) the spring constant k
b) amplitude of oscillation A
c) maxiumum velocity
d) the velocity when the mass is 0.050m from equilibrium
e) maximum acceleration of mass
f) total energy
g) kinetic and potential energy at half amplitude
h) period and frequency
