    Incline Skiing
AI Thread Summary
To calculate the angle for skiing down an incline, the inverse sine function is used, specifically theta = sin^-1(0.204). A common issue arises when calculators are set to radians instead of degrees, leading to incorrect results. When set to degrees, the correct calculation yields an angle of 11.8 degrees. Users should ensure their calculators are configured properly to avoid confusion. Proper settings are crucial for accurate trigonometric calculations in skiing scenarios.

i have a question that pertains to skiing down an incline...i can do everything for it, but i have no idea how to get 11.8 degrees from: theta=sin^-1 (0.204) though. how would i know that 11.8 is the answer?

Do you have a calculator which can calculate the inverse sine?

yea but when i do the inverse sin of .204 on my calculator i get .20544. i am not using it right?

make sure ur calculator is set to degree not radians or gradients
 
ur calculator is in radians...change it to degrees and you should get ur expected answer
 
oh my gosh thank ya'll sooo much! i have been trying to figure that out for the longest time. i am so absent minded sometimes :)
 
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}...
