Harmonic Harmonic motion Motion Oscillations Simple harmonic motion

AI Thread Summary

The discussion focuses on calculating the periodic time of oscillations for a mass-spring system performing simple harmonic motion (SHM). The mass is 0.49 kg, and the spring constant is 19.8 N/m. The relevant equation connecting the spring constant and angular frequency is k = mω², which helps derive the formula T = 2π/ω. The calculated periodic time T is approximately 0.988 seconds. Understanding these relationships is crucial for analyzing SHM in physics.

A 0.49 kg mass attached to a spring (k = 19.8 N m-1) is performing SHM on a smooth horizontal surface. Calculate the periodic time of these oscillations, in s.

what equation links with T=2pi/w to give T or how do i use a=-ky/m.
thanks in advance

if
F=ma= m*d^2y/dx^2 = -m*w^2*y = -ky
i get T=0.988

The linking equation you're looking for is:

k = m\omega^2

Thread 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

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}...

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
