[NEET-2019​

Answer 1

Answer:

y - projection of the radius vector of rotating particle  P is

$y = 3 cos(\frac{\pi}{2})t$

Explanation:

As we know that the particle start from its extreme position

So here we will have

$y = A cos\omega t$

now we know that

$\omega = \frac{2\pi}{T}$

here we have

$T = 4s$

so we will have

$\omega = \frac{\pi}{2}$

now we know that

A = maximum displacement or amplitude = 3 m

so we will have

$y = 3 cos(\frac{\pi}{2})t$
