Ch3 HW1 (Homework) Arthur Barfield PHYS 2211, section M, Fall 2008 Instructor: Jennifer Curtis Web Assign Current Score: 26.8 out of 36 Due: Tuesday, September 9, 2008 01:58 PM EDT Description Non-constant forces, including spring forces Instructions Readings: Sections 3.1-3.3 The due date for this assignment is past. Your work can be viewed below, but no changes can be made. 1. [MI2 03.X.00] 4/4 points During a time interval of one second, a ball moves in the + x or - x direction (that is, to the right or the left), and a net force acts on the ball in the + x or - x direction. For each motion listed below, check all the descriptions of net force that could produce that behavior. More than one description may be valid for a particular motion. (a) ball permanently at rest net force to the left with constant magnitude net force to the left with decreasing magnitude net force to the right with increasing magnitude net force = 0 net force to the right with decreasing magnitudenet force to the left with increasing magnitude net force to the right with constant magnitude (b) ball moving to the right at constant speed net force to the right with decreasing magnitude net force to the left with increasing magnitude
