3. Atwood’s Machine.
(a) The 3 kg weight is initially held still so that the system is
stationary. What is the tension in the string
at this time. Second block is 2 kg.
(b) The weight is then released. Does the tension in the string
stay the same, get smaller or get larger?
(c) To answer the question in part (b) quantitatively, draw free
body diagrams for each block separately.
Then write down an expression for the net force on each assuming
tension is an unknown quantity T.
Apply Newton’s second law in each case. Hence find the acceleration
of the blocks and the tension in
the string.

2. Mass mi 10.0 kg is initially held against the spring of spring constant k 100 N/m. The spring is compressed a distance x 0.45 m. When released, m, is fired towards a block of mass m 4.4 kg initially at rest at the edge of a horizontal, frictionless table of height h- 0.75 m. A ramp is placed at the end of the table. The ramp has a coefficient of kinetic friction μ-0.25 and is a distance d...

Consider the system shown in the figure right, where two blocks m1=5 kg, and m2=10 kg are connected to each other by a string that passes through a massless pulley. The stiffness constant of the spring attached to m1 and the wall is k=120N/m and the coefficient of kinetic friction between m1 and the surface is given to be μk=0.2. If the system is released from rest when the spring is at its equilibrium length and m2 is at a...

As a summer intern at UPS, you need to test the safety of a system of conveyor belts for moving packages. These are rubber sheets on which the boxes are moved from one place to another. Some of the belts are at an angle of 25 degrees from the horizontal to move boxes up or down between the warehouse and the loading docks. Your boss thinks the system works well. You are concerned about boxes slipping if the belts are...

This case presents two phases of a large business transformation project involving the implementation of an ERP system with the aim of creating an integrated company. The case illustrates some of the challenges associated with integration. It also presents the obstacles facing companies that undertake projects involving large information technology projects.
