Question 4 (1 point) A particle with charge 9.89 C travels at a speed of 53.72 m/s straight up (away from
the ground). If it's traveling through a magnetic field of strength 0.14 T that is
oriented due west, then what is the magnitude and direction of the force it
experiences?

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
