The cart travels the track again and now experiences a constant tangential acceleration from point A to point C. The speeds of the cart are 14.0 ft/s at point A and 19.0 ft/s at point C. The cart takes 3.50 s to go from point A to point C, and the cart takes 1.40 s to go from point B to point C. What is the cart's speed at point B

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
