Answer:
Time taken by the object is 0.012 s .
Explanation:
Given :
Frequency , f = 3.5 Hz .
Amplitude , A = 0.15 m .
At time t = 0 , x = 0 m.
Since , at time t = 0 , x = 0 m .
Therefore , equation of displacement is :
...equation 1.
Here , is angular frequency and is given by :
We need to find the time at which its displacement is ,
Putting all these value in equation 1 we get ,
Hence , this is the required solution.
