A force of 49 N is just sufficient to pull a block of wood weighing 10 kg on a rough horizontal surface. Calculate the coefficient of friction and angle of friction.

A 2.5 kg block is initially at rest on a horizontal surface. A horizontal force vecF of magnitude 6.0 N and a vertical force vecP are then applied to the block (Fig. 6-31). The coefficients of friction for the block and surface are mu = 0.40 and mu = 0.25 . Determine the magnitude of the frictional force acting on the block if the magnitude of vecP is (a) 8.0 N. (b) 10 N, and (c) 12 N

A 1 kg block is being pushed against a wall by a force F=75N as shown in the figure. The coefficient of friction is 0.25. The magnitude of acceleration of the block is:

Calculate the force P required to cause the block of weight W_(2)=200N just to slide under the block of weight W_(1)=100N shown in figure-2.83. What is the tension in the string AB ? Coefficient of friction mu = 0.25 for all surfaces in contact. [90 N, 20sqrt(2)N]

Two blocks A and B are connected to each other by a string and a spring , the string passes over a frictionless pulley as shown in the figure. Block B slides over the horizontal top surface of a stationary block C and the block A slides along the vertical side of C , both with the same uniform speed. The coefficient of friction between the surface and blocks is 0.5 K = 2000 N//m . If mass of A is 2 kg calculate mass of B . .

In the figure shown, a block of weight 10 N resting on a horizontal surface. The coefficent of static friction between the block and the surface mu_(s)=0.4 . A force of 3.5 N will keep the block in uniform motion, once it has been set in motion. A horizontal force force of 3N is applid to the block, then the block will

A is a 100kg block, and B is a 200kg block. As shown in figure the block A is attached to a string tied to a wall. The coefficient of friction between A and B is 0.2 and the coefficient of fricition between B and floor is 0.3. Then calculate the minimum force required to move the block B. (take g=10m//s^(2) ).

Block B rests on a smooth surface .The coefficient of static friction between A and B is mu = 0.4 where F = 30 N then Acceleration of lower block is
