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.

Time left 0:20:32 An amusement park in Dubai has a ramp which is frictionless. A child drops a smooth object and it slides down the ramp and comes down through a height 4 m. What distance is necessary to stop the object on the flat track if the coefficient of friction is 0.4? h. Answer:
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?
