A 12.1 kg box sits on a horizontal table. A string with tension 24.9 N pulls on the box to the right, but static friction between the box and the table prevents the box from moving. The coefficient of static friction between the box and the table is 0.35. What is the magnitude of the static friction force on the box?

A person applies a horizontal force of 81 to the right on box What is the magnitude of the friction force acting on the block?
2. A boy pulls a 23.0-kg box with a 230-N force at 30° above a horizontal surface. If the coefficient of kinetic friction between the box and the horizontal surface is is 0.21 and the box is pulled a distance of 22.0 m, what is the work done by the friction force on the box?
a student pulls a box of books on a horizontal floor with a force of 100 N in a direction of 37.0 degrees above the horizontal. if the mass of the box and the books is 40.0 kg and the coefficient of static friction between the crate and the dock is 0.55, what is the maximum force of friction? (Will the box move?) Show the free body diagram. (183, 167, 332 or 350 N)
A horizontal force of 207 N is applied to a 63 kg box on a hard level floor. The coefficients of static friction and kinetic friction between the box and the floor are μs = 0.55 and μk = 0.35. What is the magnitude of the force of friction on the box?
1) A 50 kg box is hanging from two strings. String #1 pulls up and left, making an angle of 65o with the horizontal on the left, and string #2 pulls up and to the right, making an angle of 80o with the horizontal on the right. Find the tension in string #2 (on the right side) 2) A box is hanging from two strings. String #1 pulls up and left, making an angle of 70o with the horizontal on...
2. A box (M-8.5 kg) sits on a table (box #1). Another box (m=6.3 kg) sits on a ramp at an angle of e= 30° (box #2). The boxes are connected to each other with a cable and pulley, as shown in the diagram to the right. The static coefficient of friction between box #1 and the table is 0.88, and the kinetic coefficient is 0.81. There is no friction between box # 2 and the ramp. (4 pts.) Draw...
