Simple Harmonic Motion - Mass on a spring

AI Thread Summary
A mass of 0.2 kg attached to a helical spring causes an extension of 0.05 m, allowing for the calculation of the spring's force constant. After being pulled down an additional 0.02 m and released, the time period of the oscillations can be determined using the spring constant. The maximum acceleration during motion can be calculated by considering the amplitude of the oscillation and the forces acting on the mass. The relationship between maximum acceleration and amplitude is crucial for these calculations. Understanding these principles will help clarify the dynamics of simple harmonic motion in this scenario.

A mass 0.2kg attached to the lower end of a light helical spring produces an extension of 0.05m.

Calculate the force constant of the spring.

The mass is pulled down a further 0.02m and released. Calculate the time period of subseuent oscillations and the maximum value of the accelartion during motion. Assume g =10ms^-2.

I am struggling with all parts of the uestion - please can you outline a method for me to follow.

Thanks alot.

Would the acceleration be g?

Thanks

Already you have enough information to calculate the spring constant, and then use it to calculate the period and frequency of the motion.

The mass is pulled down a further 0.02m and released. Calculate the time period of subseuent oscillations and the maximum value of the accelartion during motion.
So what's the amplitude of the motion? How does maximum acceleration depend on amplitude? (You can also find the acceleration by analyzing the forces on the mass.)
 

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...

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}...
