AI Thread Summary
The discussion focuses on finding the frequency, amplitude, and period of a particle's motion described by the function s = 2sin2tcos2t. The user simplifies the function to s = sin4t and calculates the amplitude as 1, the period as π/2, and the frequency as 2/π. The calculations are confirmed to be correct, assuming that the variable 2t is in radians. The thread concludes with appreciation for the assistance provided.

Hi,

I need to find the frequency, amplitude, and period for the motion of a particle whose distance s from the origin is the given function.

s= 2sin2tcos2t.

This is what I came up with, can someone please tell me if I am doing this correctly.

sin2t = 2sintcost

s = sin4t

A= 1
P= Pi/2
F= 2/Pi

Thanks.

Looks good to me. (Assuming that 2t is in radians.)
 
Thank you so much
 
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
