The coefficient of kinetic friction is independent of the angle of the incline. Hence, the coefficient of kinetic friction obtained for the three angular settings of the inclines plane is the same.

A block is at rest on an inclined plane (shown in diagram). Coefficients of friction are μ-02, μ,-0.17. Gravity is 9.8 m/s2 Okg What is the normal force on the box? Let's assume friction were not a factor-the box would slide down the ramp. What is the magnitude of the force that causes the box to24 down the ramp? What is the static friction force on the box? Will the box slide without being pushed down the ramp? What is...
Ex: Friction and inclined plane. A box of mass 10 kilograms is placed on an inclined plane so that it is at rest. The coefficients of static and kinetic friction between the surfaces of the plane and the box Are 0.4 and 0.3 respectively. a) For what value of the angle of inclination of the plane the box will start sliding down the plane ? b) Find out its acceleration as it slides down the plane.

The coefficient of kinetic friction for a block of mass 45 kg sliding down an inclined plane having an angle of 52 degrees to the ground is .03. Calculate the acceleration of the sliding block.
In the experiment to measure the coefficient of kinetic friction by sliding a block down on inclined plane, it is required that the block move at constant velocity. Why is this requirement necessary? 5. Frictional forces on a block on an inclined plane are directed down the plane (TRUE/FALSE). 9. How does the coefficient of kinetic friction depend on the constant speed of a moving object?
A block is placed on a plane that is inclined at 30 o to the horizontal. The coefficients of static and kinetic friction for the block on the inclined plane are 0.5 and 0.4, respectively. The block a accelerates down the inclined plane. b travels down the inclined plane at constant velocity. c travels up the inclined plane at constant velocity. d remains stationary on the inclined plane.
6. Inclined Plane with Friction. The inclined plane has a static mu value of 0.3. a) Find the minimum angle for movement. b) With this angle, the block now slides, with a kinetic mu of 0.2. Use Newton's Second Law to find the resulting acceleration.
A 0.3 kg ball is released in an inclined plane as shown in the figure below. In order for it to stop at point B, what is the magnitude of the kinetic friction force?
less.) The coefficient of kinetic friction between block A and the inclined plane is Mk = 0.2. Initially the blocks are moving but eventually come to stop. You will be asked to solve for different things. Please pay attention: the numbers may change from problem to problem since they are randomized. 4) If block A weighs 90 lb and block B weighs 70 lb, and initially block A moves down the plane at a velocity of 7.2 ft/s, determine how...
