A 3kg block is attached to an ideal spring with a force constant k=200N/m. The block is given an initial velocity in the positive direction of magnitude u=12m/s and no initial displacement(x.=0). (a) find the amplitude?
Conservation of total Energy
At displacement = 0:
#qquad U = 0, qquad T = T_("max")#
At maximum displacement:
#qquad T = 0, qquad U = U_("max")#
