AI Thread Summary
The discussion revolves around calculating the speed of an arrow at the peak of its flight after being launched at a 45-degree angle. Sarah has determined an initial velocity of 96.54 m/s but is uncertain about the next steps in the calculation. Participants question the accuracy of her initial velocity and seek clarification on how it was derived. The conversation emphasizes the need for further calculations to find the speed at the top of the flight. Accurate calculations are crucial for understanding projectile motion in this context.

any help is much appreciated!

Sarah sent a arrow a horizontal distance of 9.5X10^2 m. What was the speed of the arrow at the top of the flight if the arrow as launched at an angle of 45 degrees with respect to the horizontal?


i figured out the Vi, which was 96.54. But, I'm not sure what to do from there.

What did you do to find that initialvelocity? I don't think it is quite right.
 

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}...
