Question:
Complete question for this is to find the equation for this and may be the graph.
Explanation:
As for the oscillation motion, initially peak is occurring hence it will be a cosine function with peak value of 3(cm).
To calculate time period, the whole cycle should be 360°
i.e.
cos (Xπ.t) = cos (360)
as the cycle completes at 1.2 sec hence by putting t=1.2, answer should be 360.
i.e.
X*180*t=360
X*180*1.2=360
X=5/3
So, the required equation is
Graph for this equation is attached here with this answer.
In graph,
x-axis: t=0 ~ t=1.2
y-axis: f(x)=-4 ~ f(x)=4
