    Air Area
AI Thread Summary
The discussion revolves around a request for assistance with physics problems involving circular motion and projectile motion. Key questions include calculating centripetal force for an object spun on a string, determining the maximum height and time in the air for an arrow shot at a specific angle and speed, finding tangential velocity given a rotational frequency and radius, and calculating angular acceleration from a change in angular velocity. The original poster expresses confusion about how to apply the relevant equations to solve these problems. Clarification and guidance in simplifying the questions are requested to facilitate understanding.

I understand what they are asking me in these problem but I don't know how plug these numbers in the equations.
If you could help me it would be wonderful thanks.
Fc if spun on a 2.5m string at 6 radians every 10 seconds?An arrow is shot at 20 m/s at an angle from the horizontal of 37 degree.what its maximum height? time in the air?Horitzontal range

tangential velociy if rotational frequency=0.75 Hz with a readius of 4.0m

Angular accerlation if change from 10rad/pie to stopped in 3.0 seconds?

Um, no offense but I don't really understand anything you just said, could you make it a bit more clear?
 

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}...
