A toy of mass 0.151 kg is undergoing SHM on the end of a horizontal spring with force constant k = 301 N/m . When the object is a distance 1.23×10^−2 m from its equilibrium position, it is observed to have a speed of 0.297 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?
