Flywheel shaped like a solid cylinder w/ radius of 0.4999 m and mass of 10.1 kg can be brought to an angular speed of 5.88 rad/s in 0.531 s by a motor exerting constant torque. When the motor is turned off, the flywheel makes 26.8 rev before coming to rest because of friction (assumed constant during rotation).

What percentage of the power genrated by the motor is used to overcome friction????

Our high school had a person come in and do a workshop today, involving bending spoons with your mind (I'm not joking).

It had something to do with relaxing your mind, thinking about a positive image, and mentally picturing the spoon bending. Some people who concentrated very intently actually bent it (I'm not on drugs).

What's the scientific explanation for this?
