Two cars drive on a straight highway. At time t=0, car 1 passes road marker 0 traveling due east with a speed of 20.0 m/s . At the same time, car 2 is 1.00km east of mile marker 0 traveling at 30.0m/s due west. Car 1 is speeding up with an acceleration of magnitude 2.5m/s^2 , and car 2 is slowing down with an acceleration of magnitude -3.2 m/s^2 . a.)write position time equation for both cars let east be the positive direction b.) At what time do the cars pass next to one another?

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
