While driving to work one day, I was holding my coffee mug in my lefthand while changing the radio station with my right hand. Then my cellphone rang, so I placed the mug on the flat part of my dashboard.Then, believe it or not, a deer ran out of the woods and onto the roadright in front of me. Fortunately, my reaction time was zero, and I wasable to stop from a speed of 17 m/s in a mere 50 m, just barelyavoiding the deer, without the coffee mug sliding. The mug (withcoffee) had a mass of 550 g, and the mass of the deer was 150 kg.Part AWhat is the minimum possible value of the coefficient of static friction between the mug and the dashboard?Hg =

A car enters a 368-m radius horizontal curve on a rainy day when the coefficient of static friction between its tires and the road is 0.52. What is the maximum speed at which the car can travel around this curve without sliding in m/s?
Current Attempt in Progress The drawing shows a baggage carousel at an airport. Your suitcase has not slid all the way down the slope and is going around at a constant speed on a circle ((r= 11.0 m) as the carousel turns. The coefficient of static friction between the suitcase and the carousel is 0.520, and the angle in the drawing is 7.45°. How much time is required for your suitcase to go around once? Assumme that the static friction between the suitcase and the carousel is at its maximum. Number Units

In an old-fashioned amusement park ride, passengers stand inside a 3.90 m diameter hollow steel cylinder with the backs against the wall. The cylinder begins to rotate about a vertical axis. Then the floor on which the passengers are standing drops away! If all goes well, the passengers will "stick" to the wall and not slide. Clothing has a coefficient of static coefficient of friction against steel in the range of 0.690 to 1.0 and a kinetic coefficient in the range 0.480 to 0.70. A sign next to the entrance says "No children under 30 kg allowed." What is the minimum angular speed in rpm (do not enter units) for which the ride is safe? Assume that the local acceleration due to gravity is -9.80 m/s². Submit Answer Tries 0/10

An engineer is working on determining the speed limit for a curved stretch of road. She knows the coefficient of friction between the wheels and the road is 0.75 when the road is dry and 0.4 when the road is wet. She also knows that the mass of the vehicle does not matter, but completes her calculations for a 700kg car. In order to set a speed limit that is safe under any conditions, should she perform her calculations with the coefficient of friction for wet or dry pavement? wet Answer the following questions for the case when the car is traveling at the maximum speed with the road conditions selected above.

In about 1915, Henry Sincosky of Philadelphia suspended himself from a rafter by gripping the rafter with the thumb of each hand on one side and the fingers on the other side (see the figure). Sincosky's mass was 83.0 kg. If the coefficient of static friction between hand and rafter was 0.710, what was the least magnitude of the normal force on the rafter from each thumb or opposite fingers? (After suspending himself, Sincosky chinned himself on the rafter and then moved hand-over-hand along the rafter. If you do not think Sincosky's grip was remarkable, try to repeat his stunt.)
