Question

If y denotes the displacement and t denotes the time and the displacement is given by y=a sinwt ,the velocity of particle is what?

Answer 1

Answer:

velocity=aw cos wt

Explanation:

we know v=dy/dt

so,

d(a sin wt)/dt

applying chain rule,

d(a sin wt)/d(wt)*d(wt)/dt

=>a cos wt*w

=>aw cos wt
