Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

A force in the +x-direction with magnitude F(x) = 18.0 N - (0.530 N/m)x is applied to a 8.30 kg box that is sitting on the horizontal, frictionless surface of a frozen lake. F(x) is the only horizontal force on the box.
Bank robbers have pushed a 1000 kg safe to a third-story floor-toceiling window. They plan to break the window and lower the safe 10.0 m to their truck. Not being too clever, they stack up 500 kg of furniture, tie a rope between the safe and the furniture, and place the rope over a pulley. Then they push the safe out of the window. The coefficient of kinetic friction between the furniture and the floor is 0.5. The rope would break if the force on it exceeds 5000 N. a) Does the rope break? b) What is the acceleration of the safe? c) What is the safe’s speed when it hits the truck?
Bob borrows a lunch tray of negligible mass to push Will on the tray across a level portion of the field. The coefficient of kinetic friction between the tray and the grass is 0.25 and the coefficient of static friction is 0.30. Will is pushed 40m across the field by Bob at a constant speed, but Bob is so tall that he pushes with a force of 40 degrees below the horizontal. Will gained some weight during quarantine, so he now weighs 120kg. a) What power does Bob need to move Will across the field in 20sec? b) What could Bob do to decrease the work he needs to push Will across the field without decreasing his force?
A 3.00-kg block is sent up a ramp inclined at an angle 0 = 27.0° from the horizontal. It is given an initial velocity vo = 15.0 m/s up the ramp. Between the block and the ramp, the coefficient of kinetic friction is µ = 0.30 and the coefficient of static friction is µ, = 0.80. What distance D along the ramp's surface does the block travel before it comes to a stop? D =
The coefficient μ of kinetic frictions depends on the surfaces in contact and their conditions, while the coefficient μ of static frictions does not depend on the surfaces conditions. a) Trueb) False

You have been called to testify as an expert witness in a trial involving a head-on collision. Car A weighs 1515 lb and was traveling eastward. Car B weighs 1125 lb and was traveling westward at 43.0 mph. The cars locked bumpers and slid eastward with their wheels locked for 17.5 ft before stopping. You have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750 . What speed ? (in miles per hour) was car A traveling just before the collision?
