- How fast (in rpmrpm) must a centrifuge rotate if a particle 5.2 cmcm from the axis of rotation is to experience an acceleration of 200000 gg 's?A lasso is whirled making a horizontal circle 2.3 m in radius. If each revolution of the lasso requires 7s, find the centripetal acceleration of the loop.The earth orbits the sun once every π x 107 s at a distance of 1.5 x 1011 m. Assuming uniform circular motion, what is its centripetal acceleration?
- Can tangencial acceleration change the speed of a particle undergoing circular motionWhen an object is in uniform circular motion, the velocity of the object never changes. True FalseCross country runners must turn a corner around a tree obstacle, in the rain. a) The first runner takes a wide line to the tree and runs around a curve with a radius of 1.5 m and undergoes a radial acceleration of 10 m/s2. Determine their tangential velocity during the curve. b) The second runner is trying to catch up and so runs closer to the tree. If a loss of control (slip) occurs at a radial acceleration of 22 m/s2, does the runner manage to run around a curve with a radius of 0.50 m at a tangential velocity of 3.5 m/s?
