At t=0, a 650-g(0.65kg) mass at rest on the end of a horizontal spring(k=184n/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 position as a function of time (e) the total energy, and (f)the kinetic energy when x=0.4A where A is the amplitude.(adsbygoogle = window.adsbygoogle || []).push({});

a) period=2pi*sqrt0.65/184=.37

Frequency=2.07

b)v=sqrtk/m(A^2-X^2)=0.13

C) A-max=184*0.13/0.65=36.8 m/s^2

d)x=0.13cos(phi)

e)no idea

f)no idea
