in static friction questions how do you determine if you use Fr or F
Homework Answers
In static friction questions, we find the force of friction
using expression Fr = 
N where N is Normal
reaction, if this force comes out to be more than applied force F,
than we use only F, and if this force comes out to be less than F,
we use it.

A 0.4 kg block rests on a desk. The coefficient of static friction is 0.2. You push the side of the block but do not have a spring scale to measure the force you use. The block does not move. Which statement is true about the force of static friction ? - It is no larger than 0.78 N - It is 0.78 N - It is 0.08 N - It is no smaller than 0.78 N

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...

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...

Question 8 A student wants to determine the coefficients of static friction and kinetic friction between a box and a plank. She places the box on the plank and gradually raises one end of the plank. When the angle of inclination with the horizontal reaches 20°, the box starts to slip, and it then slides 2.2 m down the plank in 1.9 s at constant acceleration. What are (a) the coefficient of static friction and (b) the coefficient of kinetic...

A 39 kg crate sits on a horizontal floor. The coefficients of static and kinetic friction between the crate and floor are 0.6 and 0.4, respectively. Use a coordinate system with +y pointing upwards. a) How much force do you need to apply to get the crate sliding along the floor? [ , , ] N b) If the crate is moving with a speed of [0.8, 0, 0] m/s, what force is it experiencing due to friction as it slides? [ , , ] N...
