Another gymnast is swinging around a high bar with an initial angular velocity of 3.01 rad/s. He wishes to increase his angular motion around the
high bar to 5.62 rad/s^2 in 1.16s. What will be his angular velocity at the end
of the 1.16s interval (in rad/s)?

In an old-fashioned amusement park ride, passengers stand inside a 3.0-m-tall, 5.0-m-diameter hollow steel cylinder with their backs against the wall. the cylinder begins to rotate about a vertical axis. then the floor on which the passengers are standing suddenly drops away! if all goes well, the passengers will “stick” to the wall and not slide. clothing has a static coefficient of friction against steel in the range 0.60 to 1.0 and a kinetic coefficient in the range 0.40 to 0.70. part a what is the minimum rotational frequency, in rpm, for which the ride is safe? express your answer using two significant figures. f f = rpm
