Short Answer Question (7 points total) Directions: This question is a short free-response question. Show your work for each part of the question. A box of mass, m, is attached to the end of a string that is wrapped around a pulley. The pulley turns at a constant rate causing the box to move up the incline at a constant speed due to the tension in the string. a. In terms m, h and physical constants, determine the change in gravitational energy of the block while on the incline. b. Two students make the following claims: Student A: Since W = (Fcos0)d, the only work done on the block is the work done by the tension force. If the system is the block alone. Student B: Since W = AE, the net work done on the box is zero. With which of the students' claims do you agree with completely? Student A Student B Both students Neither students Justify your selection
