At t = 0, a 740g mass at rest on the end of a horizontal spring (k = 115N/m) is struck by a hammer, which gives it an initial speed of 2.82m/s.
a. Determine the period of the motion.
b. Determine the frequency of the motion.
c. Determine the amplitude.
d. Determine the maximum acceleration.
e. Determine the total energy.
