Question
ll tangent to the circle because there is a force on it perpendicular to the boat directed to the outside of the circle. The boat will move off to the outside perpendicular to the tangent line since a force directed to the outside of the circle always acts on the boat. e. A rock attached to a string swings in a vertical circle. Which free body diagram could correctly describe the force(s) on the rock when the string is in one possible horizontal position? N T Two small cylindrical plastic containers with flat bottoms are placed on a turntable that has a smooth flat surface. Canister A is empty; canister B contair lead shot. Each canister is the same distance r from the center. The coefficient of static friction between the canisters and the turntable is , when the speed of the turntable is gradually increased, only the lighter container slides outward off the turntable; the heavier one
Explanation / Answer
Option C is correct.
two forces act on the rock. One force is gravity which always points down.
the second is the tension force that results from the centripetal acceleration. The tension force always points to the center.
