An oscillator consists of a block attached to a spring (k = 500 N/m). At some time t, the position (measured from the system's equilibrium location), velocity, and acceleration of the block are x = 0.660 m, v = -12.3 m/s, and a = -128 m/s2. (a) Calculate the frequency of oscillation. Hz (b) Calculate the mass of the block. kg (c) Calculate the amplitude of the motion.

a) , b) , c)

Explanation:

a) The system have a simple armonic motion, whose position function is:

The velocity function is determined by deriving the position function in terms of time:

The acceleration function is found by deriving again:

Let assume that . The following nonlinear system is built:

System can be reduced by divinding the second and third expressions by the first expression:

Now, the last expression is divided by the first one:

b) The mass of the block is:

c) The phase angle is:

The amplitude is:

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
