Homework Statement A metal bar of length r is attached to a pivot point at (0,0) in the XY plane. A steel ball is projected toward the free end of the rod and strikes it at the tip. Show how to calculate the angular acceleration of the bar after the collision and draw a vector diagram to scale...

We weren't given any initial conditions other than that the block is set into motion around the cone. I was using an equation to find time so I could have all variables for the kinematic equation Vf=Vo + at

sorry, theta is 74.53 degrees. As for the whole rotates thing, this is as descriptive as our teacher was when giving us this problem. My problem statement isn't verbatim, but he never told us anything aside from what I have given. I am just as confused by this problem as you are.

Homework Statement So here is the problem, There is a .03kg block that is in an inverted cone, the cone has a slant length of 15 cm and a radius of 4 cm, and the coefficient of friction is .35. The block rotates around the inside of the cone, seamlessly, until it hits the bottom of the cone...

I really couldn't find anything too specific that related amplitude to anything in this scenario. Do you think you could give me a specific website?

Ok thank you. I don't know if you saw my earlier comment about the amplitudes of waves but could you check that out and see if there is any sense in it?

Well we never actually measured the velocity we were just asked to prove the equation however the velocity of the fundamental= 37.52 1st= 37.34 2nd= 39.92 3rd= 34.905 and to find those figures we used the equation velocity= wavelength x frequency

Update: I now realize that the greater the frequency the lower the velocity. Could the fact that at lower frequencies the string has a larger amplitude be a factor? As in at larger amplitudes the tension created by the mass at the end of the string will have to be greater in order to...

Homework Statement Here is the lab overview: In this experiment standing waves are produced in a string using a vibrator of variable frequency. The vibrator is placed under one end of the string which is tied to a rod and the other end of the string passes over a pulley and holds a suspended...
