A block of mass 6 kg is being pulled by force 24 N as shown. If coefficient of friction between block and the surface is 0.6, frictional force acting on the block is   A.36 N  B.32 NC.12 N  D.none of these

A 2.8 kg block is pushed along a horizontal floor by a force F of magnitude 19 N at an angle 𝜃 = 35° with the horizontal (Fig. 6-49). The coefficient of kinetic friction between the block and floor is 0.25. (The block initially starts at rest.)Figure 6-49(a) Calculate the magnitude of the frictional force on the block from the floor. N(b) Calculate the magnitude of the acceleration of the block. m/s2

A block of mass 1 kg lies on a horizontal surface in a truck. The coefficient of static friction between the block and the surface is 0.6, If the acceleration of the truck is 5 m/s2, the frictional force acting on the block is :A 5 N B 6 N C 10 N D 15 N

A 2.66-kg block is at rest on a horizontal floor. If you push horizontally on the 2.66-kg block with a force of 12.7 N, it just starts to move. What is the coefficient of static friction?
