Initially a 4kg mass and a 2kg mass are at rest on a friction free surface held together by a string. Between these two masses is a spring compressed by 0.1 m. At t= 0 , the string is cut and the two masses allowed to fly apart. When the masses are far apart, the velocity of the 2kg mass is 2m/s. 1) What is the velocity of the 4kg mass?? 2) Is momentum conserved in this process, i.e is...

Two masses M1=2kg and M2 are attached by a massless cord over a solid pulley wheel of mass M=4kg, and radius R=5cm. Static Friction between the cord and the pulley makes the pulley rotate counter-clockwise when the system is released from rest, M1 accelerates with a magnitude of 3.92 m/s2. a) Draw and label the forces acting on the two blocks, and the pulley.

Problem 2 Two blocks (of masses m and m,) are connected by a massless string, as shown below. They are pulled up an incline of angle θ by a constant force applied to m2, which we'll call F., for convenience. (Note that, is the tension in the rope held by the woman and is directed parallel to the incline.) There is no friction between m, and the incline, but there is kinetic friction (of coefficient ) between m, and the...
