1. The problem statement, all variables and given/known data While two forces act on it, a particle is to move at the constant velocity = (3.9 m/s) - (-3.6 m/s). One of the forces is 1 = (1.446064618687 N) + (-5.679751753869 N). What is the other force? 2. Relevant equations f=ma 3. The attempt at a solution I don't know an equation to use with velocity in it that would work for this problem. Can someone help me out?
