alright, so I found the centripetal acceleration. Would I equate that to: a=v^2/r? r being the (L)*sin29.. then that would be v?

Homework Statement A small metallic bob is suspended from the ceiling by a thread of negligible mass. The ball is then set in motion in a horizontal circle so that the thread describes a cone. Calculate the magnitude of the angular momentum of the bob about a vertical axisthrough the...

Homework Statement A cone with height h and radius R. The radius R is located at the top of the cone. We have to find moment of inertia of the cone. The disc has a radius r, height of dz, and is located z below the circular surface with radius R. Homework Equations dI = \frac{1}{2}\ dm\ r^2...

Homework Statement The suspended 2.3 kg mass on the right is moving up, the 2.4 kg mass slides down the ramp, and the suspended 7.2 kg mass on the left is moving down. There is friction between the block and the ramp. The acceleration of gravity is 9.8 m/s2. The pulleys are massless and...
