Lesson: Static FrictionPhysics
In this lesson, we will learn how to calculate the resultant force on an object that experiences static friction with a surface.
Sample Question Videos
A box is dropped onto a conveyor belt moving at 3.4 m/s. If the coefficient of friction between the box and the belt is 0.27, how long will it take before the box moves without slipping?
A box rests on the horizontal trailer of a truck. The coefficient of static friction between the box and the surface of the trailer is 0.24. The truck starts from rest and moves horizontally with constant acceleration. What maximum distance can the truck travel in 3.0 s without the box starting to slide?
The mountain climber shown is 52.0 kg. Assume that the force she exerts with her feet on the vertical rock face is parallel to her legs and the force exerted by her arms is negligible.
Find the tension in the rope.
Find the force that the mountain climber must exert with her feet on the vertical rock face to remain stationary.
Find the minimum coefficient of friction between the climber’s shoes and the cliff.
