Finding Centripetal Acceleration on Earth's Surface?

AI Thread Summary
To find the centripetal acceleration at the Equator and North Pole, the formula ac = v²/r is used, where r is the Earth's radius (approximately 6 x 10^6 m). The challenge lies in determining the Earth's rotational velocity, particularly at the Equator, where it is highest. At the North Pole, the rotational velocity is effectively zero, resulting in no centripetal acceleration. To calculate the velocity at the Equator, the distance traveled in one rotation (the circumference of the Earth) divided by the time for one complete rotation (24 hours) is required. Understanding these concepts is essential for solving the problem effectively.

Homework Statement


The problem states: Find the centripetal acceleration of a point on the Equator. Find the centripetal acceleration at North Pole, due to the rotation of Earth about its axis


Homework Equations


ac = v2/r


The Attempt at a Solution



Well I tried to make an attempt to this problem, but I don't know where to begin. All I have is the radius of the Earth which is 6 x 10 to the 6 power m (meters). This may seem like an easy problem, but I can't seem to comprehend physics at all and I would appreciate it a lot if I could get help, Thanks.

All you need now is a v. What is it at the North Pole? How would you find the Earth's rotational velocity at the equator? Velocity=distance/time.

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...
