A toy of mass 0.155 kg is undergoing simple harmonic motion (SHM) on the end of a horizontal spring with force constant 305 N/m. When the object is a distance 1.25×10^?2 m from its equilibrium position, it is observed to have a speed of 0.300 m/s.
A- What is the total energy of the object at any point of its motion?
b- What is the amplitude of the motion?
C- What is the maximum speed attained by the object during its motion?
