Please do parts d, e, 1, and 2.

**Problem Statement:** An object of mass M is connected to an object of mass m by a massless string resting over a massless, frictionless pulley. Mass M accelerates on the frictionless surface to the right.

a. Choose an appropriate coordinate system(s) and draw free body diagram(s). Make a table of known/given information and unknown/wanted information. List any physical assumptions you are using to solve the problem.

b. Write down Newton’s Second Law for both block m and block M.

c. What is the *acceleration constraint* for the two blocks?

d. Find a *symbolic expression* for the acceleration of both blocks M and m.

e. Assess the validity of your solutions in the following ways:

1) Check the physical units of your expression for the acceleration for the two blocks.

2) Consider the situation where m = 0. What do you expect the acceleration of block M to be? Does your solution from part d match your expectations in this situation? Consider the situation where \( m \gg M \) (mass m is many orders of magnitude greater than mass M). Does the resulting acceleration result make sense? Explain in words.

**Diagram Explanation:**

- The diagram shows a mass \( M \) on a horizontal surface connected to a mass \( m \) hanging vertically. Both are connected by a massless string over a massless, frictionless pulley.
- Mass \( M \) is pulled horizontally to the right, and mass \( m \) hangs vertically, creating tension in the string.
- The system assumes no friction between mass \( M \) and the surface, and no mass in the pulley or string, focusing solely on the dynamics of masses \( M \) and \( m \) with gravitational force acting on mass \( m \).
