Question 5 15 marks You should be able to answer this question after studying Unit 10 A crate, initially at rest, is pushed along a straight line up a rough ramp that makes an angle of 18° with the horizontal. The magnitude of the pushing force is 33 N, in a direction parallel to and up the ramp, and the acceleration of the crate is 0.16 ms-2. The coefficient of sliding friction between the crate and the ramp is 0.35....
Tactics Box 5.1 Working with Friction ForcesLearning Goal:To practice Tactics Box 5.1 Working with friction forces.Although friction is a complicated force, many aspects of it can be described with a simple model. This Tactics Box presents the conditions under which these models are valid and outlines the essential steps in solving friction problems.TACTICS BOX 5.1 Working with friction forces1. If the object is not moving relative to the surface it's in contact with, the friction force is static friction. Draw...
follow step by step, tanks dder, starting from rest slides down a 10-m-high hill. At the bottom of the hill is a long horizontal patch of, e bottom is μ,-0.30. How far will the sled slide along the rough patch? 1) Draw a sketch of the sledder sliding downhil, and the long horizontal patch, represent the A sled ugh snow. The hill is nearly frictionless, but the coefficient of friction between the sled and the rough snow ro before/initial and...
