A crate of eggs is located in the middle of the flat bed of a pickup truck as the truck negotiates a curve in the flat road. The curve may be regarded as an arc of a circle of radius 39.8 m. If the coefficient of static friction between crate and truck is 0.650, how fast can the truck be moving without the crate sliding?

Why is the following situation impossible? A 1.30-kg toaster is not plugged in. The coefficient of static friction between the toaster and a horizontal countertop is 0.350. To make the toaster start moving, you carelessly pull on its electric cord. Unfortunately, the cord has become frayed from your previous similar actions and will break if the tension in the cord exceeds 4.00 N. By pulling on the cord at a particular angle, you successfully start the toaster moving without breaking the cord.
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 = 8.90 m) as the carousel turns. The coefficient of static friction between the suitcase and the carousel is 0.640, and the angle in the drawing is 5.90°. 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.
This first part is at a angle of 30 degrees and it's 3 meters long. The other is at 45 degrees and it's 4 meters long. The entire ramp sits on a table that is 5 meters high. The first part is frictionless. The second part has a kinetic friction coefficient of 1. Assume that an object starts from rest on the first part and slides onto the second and then flies into the air exhibiting projectile motion under gravity. A) How far from the edge of the table will the object hit the floor? B) Total time from start to finish? C) Speed at the end of ramp 1? D) speed and velocity at the end of ramp 2? E) speed, velocity, angle when it impacts the floor?
You are working for a shipping company. Your job is to stand at the bottom of an 8.0-m-long ramp that is inclined at above the horizontal. You grab packages off a conveyor belt and propel them up the ramp. The coefficient of kinetic friction between the packages and the ramp is uk =0.30. What is the angle of the inclined ramp?
a car is driven at constant speed over a circular hill and then into a circular valley with the same radius. At the top of the hill, the normal force on the driver from the car seat is 0. The driver’s mass is 70.0 kg.What is the magnitude of the normal force on the driver from the seat when the car passes through the bottom of the valley?
A race car rounds one end of a speedway. This end of the track is a turn with a radius r of approximately 187 ft. If the track is assumed to be completely flat and the race car is traveling at a constant 62.00 mi/h around the turn, what is the race car's centripetal (radial) acceleration ac? ac = Convert this result to SI units. ac = What is the force responsible for the centripetal acceleration in this case? friction weight gravity normal ft/s² m/s²
Kinesiologists—scientists who study human motion—can measure the forces that act on runners as they round a curve. The forces on a runner’s feet are a vertical normal force that, on average, serves to counteract gravity, and a static friction force parallel to the ground and pointing toward the center of the runner’s circular path. The average value of this inward-pointing force is measured to be 600 N for a 75 kg runner rounding a curve that has a 2.5 m radius. What is this runner’s speed?
Your 1500 kg SUV enters a 35.0 m radius traffic circle. It is an icy day and the coefficient of static friction between your tire and the road is 0.15. What is the maximum speed that you can go through the traffic circle without sliding? Answer in km/h.
7. A car is right on the verge of sliding as it speeds around a level circular track. The radius of the circular track is 21 m, and the coefficient of static friction between the car's tires and the track is 0.7, while the coefficient of kinetic friction is 0.56. What is the speed of the car?
The wheels of an automobile are locked as it slides to a stop from an initial speed of 30.0 m/s. If the coefficient of kinetic friction is 0.600 and the road is horizontal, approximately how long does it take the car to stop? 4.22 s 5.10 s 8.75 s 10.4 s No answer

A jet airplane is in level flight. The mass of the airplane is m = 8850 kg. The airplane travels at a constant speed around a circular path of radius R = 9.55 mi and makes one revolution every T = 0.126 h. Given that the lift force acts perpendicularly upward from the plane defined by the wings, what is the magnitude of the lift force acting on the airplane? R L = kN
