A mass of 9 kg rests on a floor with a coefficient of static friction of 1.25 and coefficient of kinetic friction of kinetic friction of 0.1. One force is applied vertically downward of 10 Newtons and another force is applied at an angle of 15 degrees below the horizontal. Calculate what the magnitude this force needs to be in order to begin to move the mass. If the same amount of force is applied at the same angle above...
A large crate is at rest on a horizontal floor. The coefficient of static friction between the crate and the floor is 0.500. A force Fâ is applied to the crate in a direction 30.0â above the horizontal. The minimum value of F required to get the crate to start sliding is 410 N. Part A What is the mass of the crate? Express your answer with the appropriate units.
a 55-Kg box rests on a horizontal surface. The coefficient of static friction between the box and the surface is 0.30. A horizontal 42 N force is applied to the box. what is the static friction force on the box? (I know that the answer is 42 N because my teacher told me but I need the 4 questions below answered regarding this question) 1) what is the minimum static friction force? 2) how do you calculate the maximum friction...
A box with a mass of 5 kg is on a horizontal table. The coefficient of static friction between the box and the table is 0.72, and the coefficient of kinetic friction is 0.59.

A 50-N crate sits on a horizontal floor where the coefficient of static friction between the crate and the floor is .50 and that of kinetic is .40 gradually increasing horizontal force to the right is applied to the crate how would you describe the motion of the box at the moment forces reached to 20 N (a) Not moving (b) not moving bit anootbto move (c) moving with a constant speed (d) Accelerating
Friction coefficient of friction support force, sliding or static coefficient F and angle in polar format F cos-angle and F sin-angle in Cartesian x y format Vector and angle in polar format - Vector cos-angle and Vector sin-angle in Cartesian x-y format Force, velocity, acceleration are vector examples A system consisted of two objects sitting on a floor, a 15 kg object on top with a 50 kg object at the bottom. The sliding coefficient of friction between the two...
You are trying to determine the coefficient of static friction between your shoe and the floor. To do so, you place your shoe on the ground, attach a spring scale, then pull horizontally on the shoe until it just barely starts to move. You take note of the spring scale reading at that moment. Then you put some known extra masses into your shoe and repeat the process several times. (a) What is the purpose of adding extra masses and...
