You push horizontally on a block sitting on a table to try to get it moving. Describe how large the frictional force is in terms of the applied force and/or the normal force. The discussion should include consideration of an applied force that is increased from zero up until it causes the block to move at constant speed.

A 3.00-kg block starts from rest at the top of a 27.5° incline and slides 2.00 m down the incline in 1.30 s. (a) Find the acceleration of the block. m/s² (b) Find the coefficient of kinetic friction between the block and the incline. (c) Find the frictional force acting on the block. N (d) Find the speed of the block after it has slid 2.00 m. m/s

Problem 3: A 38.8-kg crate is being pushed at a constant speed by a force of 311 N at an angle of 29 degrees below the horizontal, as shown. Part (a) What is the coefficient of kinetic friction between the crate and the floor? Numeric : A numeric value is expected and not an expression. Uk = Part (b) If the force is pulling at 29 degrees above the horizontal instead of below, as shown, what is the acceleration of the crate in m/s2, assuming the coefficient of friction is the same as in the previous part? Numeric : A numeric value is expected and not an expression. a =

A 40 N box is resting on a table when a 20 N force is applied to it horizontally. The coefficients of static and kinetic friction are 0.3 and 0.1, respectively. Which of the following best describes the resulting motion of the box?    The motion of the box cannot be determined with the given information.      The box accelerates in the direction of the applied force.      The box remains at rest.      The box moves with a constant velocity in the direction of the applied force.

You are helping a friend move. Consider two boxes which have masses in factors ofm; one of mass 6m and the other of mass 7m. The coefficient of static friction betweenthe two boxes is very large. The coefficient of static friction between the boxes and thefloor is 0.7 and the coefficient of kinetic friction is 0.1. You place the large box on top ofthe small box and slide them down a 1m high ramp out of the truck. The ramp isfrictionless because it is covered with wheels. The box slides down this ramp smoothlyonto the horizontal grass with coefficient of kinetic friction is 0.142857142857143. Howfar (in meters) will the boxes slide before they stop?

What is the cofficient of static friction between the pavement and the car tires?

A block with a mass (m) of 74.7 kg slides along a horzontal surface. the coefficent of kinetic friction is .31. THe block has an ititial speed (v0) at 11.6m/s in the positive direction.  1) write and expression for the x component of the frictional force of the block experiences Ff in terms of the given variables and variables avaible.  2) what is the magnitude of the frictional force? 3) how for will the block travel before coming to rest.

A truck is towing a 10,000-N car at a constant speed up a hill that makes an angle of a=5.0° above the horizontal. A rope is attached from the truck to the car at an angle ß=10.0° above the horizontal. (Friction is negligible.) (a) Draw a free-body diagram showing the forces acting on the car. Indicate the angle that each force makes either with either the vertical or horizontal direction. (b) What is the tension in the rope?
