Two blocks with mass M1 and M2 are arranged as shown with M sitting on an inclined plane
Two blocks with mass M1 and M2 are arranged as shown with M sitting on an inclined plane and connected with a massless unstretchable string running over a massless, frictionless pulley to M2, which is hanging over the ground. The two masses are released initially from rest. The inclined plane has coefficients of static and kinetic friction μs and μk respectively where the angle θ is small enough that mass M1 , would remain at rest due to static friction if...

4. Consider the blocks on the inclined surface above. They are attached by a steel rod that does not bend. Suppose the mass of block m 1=15 kg and has a coefficient of kinetic friction μ_k=.2, and a coefficient of static friction μ_s=.9 and θ=42 degrees. Suppose the mass of the second block is m2=25 kg.a. Suppose the masses are initially at rest. What is the minimum coefficient of friction of m2 required to stop both of them from sliding...

Two blocks with masses 4.00 kg and 8.00 kg are connected by a string and slide down a 30.0° inclined plane as shown in the figure below. The coefficient of kinetic friction between the 4.00 kg block and the plane is 0.20; that between 8.00 kg block and the plane is 0.30. A. Calculate the tension in the string. B. Calculate the acceleration of each block.

Two blocks with masses m1 and m2 are connected by a massless string over a frictionless pulley. Block 1 sits on a frictionless horizontal surface and block 2 sits on a plane inclined at an angle θ above the horizontal. The coefficient of friction between block 2 and the incline is µk. The pulley, which is a uniform disk, has a mass mp and a radius R. When you release the blocks, both blocks slide without the string slipping on...

The two blocks shown have equal masses. The coefficients of static and kinetic friction are equal to 0.30 for both blocks. If the system is given an initial speed of 0.90 m/s to the left, how far will each block move before coming to rest, assuming that the inclines are quite long? Na ma 63 30 f 53 mn 1mg

Two Masses, a Pulley, and an Inclined Plane
Block 1, of mass m1 = 0.550kg , is connected over an
ideal (massless and frictionless) pulley to block 2, of mass
m2, as shown. For an angle of ? = 30.0? and a
coefficient of kinetic friction between block 2 and the plane of
? = 0.400, an acceleration of magnitude a =
0.500m/s2 is observed for block 2.

A block of mass m is initially at rest at the top of an inclined plane, which has a height of 5.6 m and makes an angle of θ = 21° with respect to the horizontal
A block of mass m is initially at rest at the top of an inclined plane, which has a height of 5.6 m and makes an angle of θ = 21° with respect to the horizontal. After being released, it is observed to be traveling at v = 0.55 m/s a distance d after the end of the inclined plane as shown. The coefficient of kinetic friction between the block and the plane is μp = 0.1, and the coefficient...
