AI Thread Summary
The centripetal acceleration of a car negotiating a flat circular curve with a radius of 50 m at a speed of 20 m/s is calculated using the formula A_c = V^2/R. Substituting the values, the calculation yields 8 m/s². The maximum centripetal force provided by static friction is noted but does not affect the calculation of acceleration directly. Some participants express confusion over the relevance of additional details provided in the problem. Ultimately, the focus remains on the straightforward application of the centripetal acceleration formula.

Homework Statement



A car is negotiating a flat circular curve of radius 50 m with a speed of 20 m/s. The maximum centripetal force (provided by static friction) is 1.2 × 104 N. What is the centripetal acceleration of the car?


Homework Equations



MAc = MV^2/R

The Attempt at a Solution



20^2 / 50 = 8 m/s^2 ?

Not sure, but I think you're right. I have no idea what the second sentence actually means, but it might just be a red herring. Cent acc is just velocity squared over radius, and they gave you that in the first sentence.

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...
