Physics , please help me Lamia noticed while she was riding a bicycle, a broken tree blocking the road at a distance of 42 meters. If the coefficient of kinetic friction between the tires of her bike and the road was 0.36, while she was driving her bike at a speed of 25.0 km h, what distance would be required to stop, knowing that the mass of Lamia and the bike together is 95 kg

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.

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
