Question

what is position of particle when it is a p1and when it is at p2​

Answer 1

Answer:

If they are at their positive extreme positions, then Asinω t will become Acosω t Let x2 be the one with the lesser amplitude.

Answer 2

If they are at their positive extreme positions, then Asinωt will become Acosωt

Let x

2

be the one with the lesser amplitude. It is less than that of x

by 12cm. So ⟶

=Acosωt

x

=(A−12)cosωt

Substituting in 1st equation, we get

Acosωt−(A−12)cosωt=12cosωt

Since T=12sec and ω=

T

, we get ⟶

12cosωt=12cos(
