Student Name: AP Physics 1 Semester Exam-Part II (Free Response) 20 points Directions: Three forces are acting on a 5-kg mass. The vector forces are shown below. Answer the following questions and then scan this response in to be attached to this exam. Be sure to show all your work for maximum points on this question! 15 45 deg 30 deg 6 22 a) Find the vector sum of the forces using the component method. Give both the resultant magnitude and direction and sketch the resultant vector. b) What is the acceleration of the 5-kg mass if acted on by the resultant force? Student Name: AP Physics 1 Semester ExamPart II (Free Response) c) If the object is on a frictionless surface, and it starts at rest, in how many seconds will it be travelling at 12 m/s? d) Once travelling at 12 m/s, the force is removed and the object is coasting. If it then starts sliding up a 20-degree frictionless slope, how many meters along the slope will the object slide until it stops? Use energy conservation on this part.
