1. Do you use the equation of continuity and Bernoulli's equation simultaneously in a question? When do you use them?
2. In simple harmonic motion, why is the velocity shifted to left of the displacement by pi/4?
pressure + .5density x velocity ^2 + density x g x y (initial)= the same thing (final)
x(t)=xmaxcos(wt + phi) here w=omega
