A 0.156kg toy is undergoing SHM on the end of a horizontal spring with force constant 306 N/m. When the object is 1.4 x 10^-2m from its equilibrium position, it is observed to have a speed of 0.320 m/s.
Find the total energy of the object at any point in its motion?
Find the amplitude of the motion?
Find the maximum speed attained by the object during its motion?
