A toy of mass 0.145kg is undergoing simple harmonic motion (SHM) on the end of a horizontal spring with force constant 300N/m . When the object is a distance 1.15×10-2m from its equilibrium position, it is observed to have a speed of 0.305m/s .
What is the total energy of the object at any point of its motion?
What is the amplitude of the motion?
What is the maximum speed attained by the object during its motion?
