Question

The displacement of velocity undergoing simple harmonic motion is given by the equation. 
 
 Y =3sin(8pi)t , where Y is in meters and t is in seconds 

a) what is the amplitude of the motion?
b) what is the frequency of the motion?
c) what is the displacement velocity and acceleration at t=0?
​

Answer 1

Answer:

A.Amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. ... The amplitude of a pendulum is thus one-half the distance that the bob traverses in moving from one side to the other.

b.Frequency, , is defined as the rate of rotation, or the number of rotations in some unit of time. Angular frequency, , is the rotation rate measured in radians.

c.Velocity is defined as the ratio of net displacementand time taken . It is a vector quantity and its direction is in the direction of net displacement. if displacement is zero(intial and final position is same) then itsvelocity is zero.
