If you add two velocity vectors going in opposite directions, will the resultant vector be smaller or larger than the vectors you are adding? choose the correct answer with the correct reasoning. question 11 options: smaller, because the vectors are added to each other and increase the velocity larger, because the vectors are added to each other and increase the velocity smaller, because part of the velocities cancel each other out larger, because the part of the velocities cancel each other out

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
