Conservation of angular momentum of a stick
Oh ok, I didn't think you could assume that clay is a point mass. If you do that, the angular velocity if 50 rad/s... Is that correct?- 234jazzy2

Conservation of angular momentum of a stick
So, ωf = ((mb)vr1)/(I + (mb)) , where r1 = 0.25 m (half of the half...) I = (1/12)(ms)r^2 (r = 0.5 m (half of the stick) ωf = 10.526 rad/s- 234jazzy2

Conservation of angular momentum of a stick
Homework Statement A uniform stick 1.00 m long with a total mass of 270 g is pivoted at its center and is initially stationary. A 30 g piece of clay is thrown at the stick midway between the midpoint of the stick (pivot) and one end. The clay piece is going at 50 m/s and sticks to the stick...- 234jazzy2

A ball is swung in a circular path
(Sin^2(theta))/( cos(theta)) = some number. I tried using some trig identities but nothing seemed to work. As I write this, I think I could've solved it, because that also equals (1 - cos^ 2(theta))/ cos(theta) = something and set x = cos(theta) and sove the quadratic. But that will give two...- 234jazzy2

A ball is swung in a circular path
Yea, i get suck at the trig. And, it's definitely not trial and error. Trying different reference frame to see if I can get rid of a trig.- 234jazzy2

A ball is swung in a circular path
Homework Statement A 0.5 kg ball is swung in a circular path from a 80 cm long rope, attached to a vertical pole. A. What is the speed of the ball theta (between the pole and rope) is 40 deg? B. What is the KE of the ball at theta = 40 deg? C. The ball slows down and the KE drops to 50% of the...- 234jazzy2

Find the moment of inertia of this disk
Homework Statement A crucial part of a piece of machinery starts as a flat uniform cylindrical disk of radius R0 and mass M. It then has a circular hole of radius R1 drilled into it. The hole's center is a distance h from the center of the disk. Find the moment of inertia of this disk (with...- 234jazzy2
