Circular Motion of space station

AI Thread Summary
To achieve an artificial gravity acceleration of 8.0 m/s² in a circular space station with a diameter of 500 m, the required revolutions per minute (RPM) must be calculated using the formula for centripetal acceleration. For simulating Martian gravity at 3.70 m/s², a different RPM will be necessary. The discussion emphasizes the importance of understanding uniform circular motion and centripetal acceleration to solve these problems. Participants are encouraged to apply the relevant equations and share their progress. The focus is on utilizing physics concepts to determine the necessary RPM for both scenarios.

Homework Statement



4) A circular space station rotates to provide an “artificial gravity” at the outside rim.
a) If the diameter of the space station is 500m, how many revolutions per minute are needed in order for the “artificial gravity” acceleration to be 8.0 ms-2?
b) If the space station is a waiting area for travellers to Mars, it might be desirable to simulate the acceleration due to gravity of the Martian surface (3.70 ms-2). How many revolutions per minute are needed in this case?

The Attempt at a Solution



Don't know where to start:(

Look up centripetal acceleration.
 
As a body moves in a circle at a constant speed, it is said to be in uniform circular motion. You can apply this concept to the space station scenario with the formula for centripetal acceleration in regards to uniform circular motion which is as follows:[PLAIN]http://www4d.wolframalpha.com/Calculate/MSP/MSP58019ch44b53a75489i000064hd048a5c41b9hb?MSPStoreType=image/gif&s=32&w=211&h=147

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}...
