(II) At t=0 an 885-g mass at rest on the end of a horizontal spring (k=184 N/m)is struck by a hammer which gives it an initial speed of 2.26 m/s Determine (a) the period and frequency of the motion, (b) the amplitude,(c) the maximum acceleration, (d) the total energy, and (e) the kinetic energy when x=0.40 A where A is the amplitude.
(II) A mass resting on a horizontal, frictionless surface is attached to one end of a spring; the other end is fixed to a wall. It takes 3.6 J of work to compress the spring by 0.13 m. If the spring is compressed, and the mass is releasedfrom rest, it experiences a maximum acceleration of 12 m/s2 Find the value of (a) the spring constant and (b) the mass
