Please help me find the coefficient of kinetic and static friction of two masses (500kg and 300kg) show work please! Object description Mass (kg) Average of the Max force (N) Average of the average force (N) Static friction coefficient Kinetic friction coefficient Black hook weight 500 -0.09 -3.10 Black hook weight 300 -0.06 -2.15 thank you :)
7) A 2.50-kg block is on a 53.0⁰ incline for which coefficient of kinetic friction = 0.25 and coefficient of static friction = 0.50. Find its acceleration given that: (a) it is initially at rest; (b) it is moving the slope; (c) it is moving down the slope.
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...
Which statement about friction and normal force is true? a. Kinetic friction is always in the direction of the normal force. b. Static and kinetic friction do not depend on the normal force. c. Static and kinetic friction forces are linearly related to the normal force. d. Static friction is always in the direction of the normal force.
A 60kg box rests on a floor with a coefficient of kinetic friction of 0.600 and a coefficient of static friction of 0.800. What horizontal force is required to start the box moving? Please show work!
Kinetic friction will always be greater than static friction? True False

with 5 and 6 with a diagram..
kinetic friction for this case in terms of the suspended masses, the mass of the block, and the angle of decline. (Neglect any friction and mass effects of the pulley.) 5. Draw and justify conclusions about the validity of the empirical rules for friction based on your experimental results. What does this tell you about applying general rules to all materials and about the nature of friction? 6. It is sometimes said...
Kinetic friction is more difficult to overcome than static friction. True or False
7) A crate is being pushed horizontally on a flat surface with kinetic friction coefficient µk = 0.28. The push force is 36 N and its acceleration is 1.2 m/s2 , a) Draw a free-body diagram and write both components of Newton’s Second Law. b) Replace into one equation from the other one and solve it to find the crate’s mass.
The coefficient of static friction is 0.5 and coefficient of kinetic friction is 0.4. The mass of the block is 48Kg, as shown in the figure. Draw free body diagram Calculate the acceleration.
