Label parts (e.g., A, B, C) and sub-parts (e.g., i, ii, iii) as needed. Use a pencil or a pen with black or dark blue ink to write your responses.  \nA calculator is allowed in this section, as well as a ruler and straightedge. You may use a handheld four-function, scientific, or graphing calculator, or the calculator available in this application. Reference information, including lists of equations, can also be accessed in this application and is available throughout the exam.  \nAll final numerical answers should include appropriate units when applicable. Credit for your work depends on demonstrating that you know which physical principles to apply in a particular situation. Credit will be awarded only for work that is clearly designated as the solution to a specific part of a question. Credit also depends on the quality of your solutions and explanations. Therefore, you should show your work for each part in the space provided for that part. If you need more space, be sure to clearly indicate where you continue your work. When constructing a graph or diagram, use only one color of ink or pencil.  \nYou may pace yourself as you answer the questions in this section, or you may use these optional timing recommendations:  \nIt is suggested that you spend about 25 minutes each on Questions 1 and 3, about 30 minutes on Question 2, and about 20 minutes on Question 4.  \nYou can go back and forth between questions in this section until time expires. The clock will turn red when 5 minutes remain—the proctor will not give you any time updates or warnings.  \nNote: This exam was originally administered digitally. It is presented here in a format optimized for teacher and student use in the classroom.  \nDuring the AP Exam administration, students have access to reference information.

A student has a cart of mass mc and a block of mass 15~~ ~~ mc , as shown in Figure 1.  \n• At time t = 0 , the cart is moving to the right across a horizontal surface with constant speed vc , and the student releases the block from rest.  \n• At t = t1 , the block collides with and sticks to the top of the cart. The block does not slide on the cart.  \n• At t = t2 , the block-cart system continues to move to the right with constant speed vf.  \nFigure 1  \nA.  \ni.
