A block A with a mass of 3 kg rests on a horizontal table top. The coefficient of kinetic friction, μk = 0.5. A horizontal string is attached to A and passes over a massless, frictionless pulley, and block B with mass 2 kg hangs from it. Because of the pull of gravity, the masses accelerate. What is the Tension in the string (in Newtons)?

A bead of mass M is able to move without friction along a stationary horizontal rod (directed along the x axis). In addition, a second body of mass m is attached to the first bead and suspended below it via a massless rod of length a. This second mass and rod form a pendulum that is able to swing in the xy-plane (where y is the vertical axis). (a) Obtain the Lagrangian for the system of two masses. (b) Assuming...

A block of mass .5kg is ona table and attached to a block of mass .25kg by a taut massless string. The .25kg block hangs by means of the string, which goes over a pulley. The .25kg block is released, and it descends from rest at a constant acceleration, travelling 1.00m in 1.25s. What is the coefficient of kinetic friction between the table and the .5kg block?
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...

A uniform, solid cylinder with mass 3M and radius 2R rests on a
horizontal tabletop. A string is attached by a yoke to a
frictionless axle through the center of the cylinder so that the
cylinder can rotate about the axle. The string runs over a
disk-shaped pulley with mass M and radius R that is mounted on a
frictionless axle through its center. A block of mass M is
suspended from the free end of the string (the figure...

Block A has a mass of 2.87 kg and block B has mass 1.98 kg.
Block B is at the height ℎ = 1.50 m when the blocks are released
from rest. Determine the speed of block B just before it bumps into
the ground:
(a) if block A slides frictionlessly along its horizontal
planet; and
(b) if the sliding friction number between block A and the
ground is 0.18.
(Assume that the string and pulley have negligible masses and...

Problem 5 (15 points) A small bead can slide without friction on a circular hoop that is a vertical plane and has a radius of 0.100 m. The hoop rotates at a constant rate of 4.00 rev/sec (recall 1 rev = 2π rad) about a vertical diameter as shown in the figure below (a) Find the angle β at which the bead is in vertical equilibrium. (It has a radial acceleration toward the axis.) (b) Is it possible for the...

M 3. A mass M, = 13.4 kg is on a horizontal surface. This mass is connected to a rope which runs over a frictionless massless pulley to a hanging mass M. = 9.56 kg. The coefficient of kinetic friction between M, and the surface is 0.257, and the coefficient of static friction is 0.355. a) Assuming that the masses are moving, find their acceleration b) M. is now changed, and the system is stopped and released.

A block of mass m1= 4.00 kg moves on the surface of a horizontal
table. The coefficient of kinetic friction k between the table top
and m1 is equal to 0.350. Block 2 of mass m2= 2.00 kg is tied to m1
via a string that passes over a frictionless, massless pulley. The
two blocks start from rest and m2 drops by a distance L =1.75 m to
the floor.
