A toy of mass 0.155kg is undergoing simple harmonic motion (SHM) on the end of a horizontal spring with force constant 295N/m . When the object is a distance 1.15×10^-2 m from its equilibrium position, it is observed to have a speed of 0.305 m/s. What is the amplitude of the motion? What is the maximum speed attained by the object during its motion?
