A sled is on a horizontal surface and a rope with tension T is pulling on it at an angle 0 above the horizontal. The sled had mass M and does not move due to the frictional force. In this case the coefficient of friction is µ̟. In terms of the variables given and g, what is the magnitude of the frictional force in this case? Select one: a. H, Mgsino b. Tcose O c. Tsin0 O d. H, Mgcos0

A physics textbook is placed on an inclined slope with an adjustable angle a. The coefficients of friction between the book and the slope are us = 0.5 and uk = 0.35 %3D respectively. 1m a (i) Initially the book is not moving. Copy the diagram and draw all the forces acting on the book. Show mathematical expressions for the size (magnitude) of each force. If we slowly increase the angle a, at what angle does the book start sliding? (ii) Use the Work-Energy theorem to find a formula (expression) for the speed v of the book when it reaches the bottom, in terms of the angle a.

A man pulls a 50.0-kg block of ice with a rope over his shoulder as shown below. Suppose that he applies just enough force to get the block moving and then he continues to apply the same force. If it takes 2.00 seconds for the block to move 3.00 meters and if the coefficient of kinetic friction between the block and the surface is ?? =0.100, determine the coefficient of static friction ?? between the block and the surface. You may assume that the acceleration of the block is constant.

You and your friend are moving a 82kg box across the floor at a constant speed.  You are pushing on the crate parallel to the ground with a force of 62N.  Your friend has a rope tied to the box and they are pulling it at an angle of 37° to the ground with a force of 32N. Construct the free body diagram showing the force acting on the crate in order to find the magnitude of friction the floor exerts on the box.
