At t=0, an 870-g mass at rest on the end of a horizontal spring (k = 188 N/m ) is struck by a hammer which gives it an initial speed of 2.22 m/s . Determine the period of the motion.
Determine the frequency of the motion.
Determine the amplitude.
Determine the maximum acceleration.
Determine the total energy.
Determine the kinetic energy when x=0.40A where A is the amplitude.
