Two boxes are connected to a rope, and the rope is hung over a pulley connected to the ceiling
Two boxes are connected to a rope, and the rope is hung over a pulley connected to the ceiling, as shown in the figure below.The masses of the boxes are m1=18.0 kg and m2=12.0 kg, the mass of the pulley is M=5.00 kg, and the radius of the pulley is R=0.300 m. Box m2 is initially on the floor, and box m1 is initially 4.70 m above the floor when it is released from rest. The pulley's axis has negligible...

connected as shown.
The pulley is light and frictionless. Find the mass

Two masses are connected on a frictionless pulley. M1 = 9 kg sits on a frictionless horizontal surface and is connected to a spring with a spring constant of k = 250 N/m. M2 = 6kg and hangs off the edge of the surface. Initially, both masses are at rest and the spring is at its equilibrium. After the blocks are released, how fast will they be moving when mass 2 falls .1 m?

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.

Rope connected two objects in the inclined plane, A block of mass m1 = 22.9 kg is at rest on a plane inclined at Theta = 35.0 degree above the horizontal. The block is connected via a rope and mass less pulley system to another block of mass m2 = 26.1 kg. as shown in the figure. The coefficients of static and kinetic friction between block 1 and the inclined plane Is MU_s is unknown. If the blocks are released...

A crate of mass m1 = 11.4 kg is pulled by a
massless rope up a 36.9° ramp. The rope passes over an ideal pulley
and is attached to a hanging crate of mass m2 =
16.3 kg. The crates move 2.70 m, starting from rest. Find the final
speed of the sliding crate if the incline is frictionless.

Since energy is conserved and nonconservative forces do no work,
mechanical energy is conserved. Let the y-axis point
