a 1.8-kg collar a and a 0.7-kg collar b can slide without friction on a frame, consisting of the horizontal rod oe and the vertical rod cd, which is free to rotate about its vertical axis of symmetry. the two collars are connected by a cord running over a pulley that is attached to the frame at o. at the instant shown, the velocity va of collar a has a magnitude of 2.1 m/s while a stop prevents collar b from moving. when the stop is suddenly removed collar b slides upward toward point o and collar a moves toward e. as collar a reaches a distance of 0.12 m from o, the magnitude of its velocity is observed to be 2.5 m/s. determine at that instant the magnitude of the angular velocity of the frame and the moment of inertia of the frame and pulley system about the vertical axis cd.

You are driving directly behind a pickup truck, going at the same speed as the truck. a crate falls from the bed of the truck to the road. (a) will your car hit the crate before the crate hits the road if you neither brake nor swerve? (b) during the fall, is the horizontal speed of the crate more than, less than, or the same as that of the truck?

I'm thinking it's 2 you are asked to explain the earth's magnetic field. which is the best reply? 1. the earth's magnetic south is similar to the north pole of a magnet. 2. the earth's core has a strong magnetic charge similar to the south pole of a magnet. 3. the earth's geomagnetic south is similar to the south pole of a magnet. 4. the earth's magnetic charge is not centered at either pole; it varies based on location.
