1. A weight suspended from a spring is set into oscillating motion by compressing it to a
Naya [18.7K]

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

f(x)=3.cos(5\frac{\pi }{2}.t)

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
