I figured out 1 and 3, can someone help me with number two though?

I am stuck on three questions :( Formulas: nsin(x)=n sin (x) sinx=n2/n11. A ray of light traveling in air strikes the surface of a liquid. If the angle of incidence is 26.0◦ and the angle of refraction is 19.3◦, find the critical angle for light traveling from the liquid back into the air. This...

Interesting! I am still at a loss as to how to find the force exerted by the pilot :(

the acceleration and netforce is correct! and what is the slide rule?

Can someone help me with part 3 of the problem? For the acceleration I got 10.97670251m/s^2 and for the Net force I got 603.7186381 N I did fn-fg=fnet and got fn=1142.718638 and it was wrong

Nope, normal high school physics.

haha! If only it was that easy, we are assigned problems online through UTexas, and so the answer has to be exact to get the question right.

Wow. I feel so stupid. That is like one of the basic parts of physics. I got 6.66488889 which was right. Thanks for your help :)

Homework Statement A 1.62 kg object is swung in a vertical circular path on a string 1.8 m long. The acceleration of gravity is 9.8 m/s^2. If the speed at the top of the circle is 5 m/s, what is the tension in the string when the object is at the top of the circle? Answer in units of NHomework...

Did I use the correct equation? And sorry about that, I just labeled part 2!

Homework Statement *Part 1* A satellite is in a circular orbit 4000 km above the Earth’s surface; i.e., it moves on a circular path under the influence of nothing but the Earth’s gravity. Find the speed of the satellite. The radius of the Earth is 6.37 x10^6 , and the acceleration of gravity at...

I got it, thanks!

What would m2, v2i, and v2f be?

Homework Statement A(n) 9 g bullet is fired into a 396 g block that is initially at rest at the edge of a frictionless table of height 0.9 m. The bullet remains in the block, and after impact the block lands 2.3 m from the bottom of the table. The acceleration of gravity is 9.8 m/s. Homework...
