Chapter 2.1, Problem 1bT
Describe the remaining forces you have indicated above in a similar fashion.
The diagram you have drawn is called a free-bodydiagram.A free-body diagram should show only the forces exerted on the object or system of interest (in this case, forces exerted on the block). Check your free-body diagram and, if necessary, modify it accordingly.
A proper free-body diagram should not have anything on it except a representation of the object and the (labeled) forces exerted on that object. A free-body diagram never includes (1) forces exerted by the object of interest on other objects or (2) sketches of other objects that exert forces on the object of interest.

Consider the system in the picture below: a cart of mass M with a static friction coefficient u
is connected through a massless string to a hanging mass m. M is a capital letter, m is lower
case. Write them as such, or vour equations will be confusing,
M
We want to find the maximum value of the hanging mass m such that the system is in
equilibrium.
1. Free body diagram (FBD): Draw a FBD for each: the Cart and the hanging mass. Clearly
show all the forces.
2. Clearly write the equilibrium equations for the cart in the horizontal and vertical direction.
3. Clearly write the equilibrium equation for the hanging mass.
4. Solve the system of the three equations above for the hanging mass m. Show your calculation to get
credit.
5. What would happen if mass m exceeds this value? Explain.
Two blocks of masses m1 and m2 are placed in contact with each other on a frictionless horizontal surface. A constant horizontal force F is applied to the block of mass m1, as shown in Figure below (right). Determine the magnitude of the acceleration of the two-block system.
Initially, the system of objects shown in the figure below is held motionless. The pulley and all surfaces are frictionless. Let
the force F be zero and assume that m, can move only vertically (with respect to the ground). At the instant after the
system of objects is released, find each of the following. (Note: The pulley accelerates along with object M. Use the
following as necessary: m₁, m₂, M, and g, where g is the magnitude of the gravitational acceleration. Do not substitute
numerical values; use variables only. Take the rightward and upward directions to be positive. Indicate the direction with
the sign of your answer.)
