A popular trick of many physics teachers is to swing a pail of water around ina vertical circle fast enough so that the water doesn’t spill out when the pail is upside down. If Mr. Campoverde’s arm is 0.60 m long, what is the minimum speed with which he can swing the pail so that the water doesn’t spill out at the top of the path, meaning it has a centripetal acceleration of 10m/s2?

To test their stamina, astronauts are subjected to many rigorous physical tests before they fly in space. One such test involves spinning the astronauts in a device called a centrifuge that subjects them to accelerations far greater than gravity. With what linear speed would an astronaut have to spin in order to experience an acceleration of 3 g’s at a radius of 10.0 m? (1 g = 10.0 m/s2)
