Ch5 HW2 (Homework) BRANDON JARROTT FELDKAMP PHYS 2211, section M, Fall 2008 Instructor: Jennifer Curtis Web Assign Current Score: 19 out of 20 Due: Wednesday, October 1, 2008 09:00 AM EDT Description Work and change in particle energy Instructions Reading: Sections 5.3-5.4 The due date for this assignment is past. Your work can be viewed below, but no changes can be made. 1. [MI2 05.X.12.01] 4/4 points An object which is originally at location < -18 , 0, 0 > m moves to location < -21 , 0, 0> m as shown in the diagram above. While it is moving it is acted on by a constant force of < 28 , 0, 0 > N. How much work is done on the object by this force? W = -84 -84 J As a result, the kinetic energy of the object decreases decreases A different object moves from location < -21 , 0, 0 > m to location < -18 , 0, 0 > m, as shown above. While it is moving it is acted on by a constant force of < 28 , 0, 0 > N. How much work is done on the second object by this force? W = 84 84 J As a result, the kinetic energy of the object increases increases Solution or Explanation Ch5 HW2 http://www.webassign.net/v4cgibfeldkamp3@gatech/student.pl?z=2008. .. 1 of 5 11/18/2008 6:22 PM

If the work done on a particle is negative, the kinetic energy of the particle decreases; if the work done is positive, the kinetic energy of the particle increases. 2. [MI2 05.X.13.01] 4/4 points
