(a) Find the total energy of the system. X The answer has units of milli-Joules not Joules. mJ (b) Find the speed of the object when its position is 1.15 cm. (Let 0 cm be the position of equilibrium.) X At this point the energy is partially stored as potential energy of the spring and partially as kinetic energy of the object. (c) Find the kinetic energy when its position is 3.00 cm. X You should be solving this problem without considering the mass of the object. mJ ..(.d.).
