Acceleration Centripetal Centripetal acceleration

AI Thread Summary

The centripetal acceleration required to keep a 0.5 kg mass moving at 0.1 m/s in a circular path with a radius of 0.2 m is calculated using the formula a = v^2/r. Substituting the values gives a = 0.1^2/0.2, resulting in an acceleration of 0.05 m/s² directed towards the center of the circle. The calculation appears correct, confirming that the centripetal acceleration is indeed 0.05 m/s². There is some uncertainty expressed about the result, but the math checks out. This confirms the necessary centripetal acceleration for the given parameters.

Homework Statement

what is the magnitude and direction of the centripetal acceleration necessary to confine the motion of a 0.5kg mass moving at speed 0.1m/s to a circular path 0.2m in radius

Homework Equations

a = v^2/r

The Attempt at a Solution

0.1^2/0.2 = a

a = 0.05m/s/s towards the centre

Doesn't look right to me

Thanks in advance

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 '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}...
