1. The problem statement, all variables and given/known data Question: An object traveling at a constant speed of 22m/s begins to experience a force of 15N in the opposite direction of its motion. (Hint given: Start by finding objects acceleration) a. How long will it take for the 8kg object to come to a complete stop once it experiences the force? b. If the object was traveling in a straight line, how far did the object travel as it slowed down? 2. Relevant equations I am not exactly sure what the relevant equations are for this problem but here are the equations we have used so far in this unit. F=ma W=mg Fs=μsxFn (Static friction=mu times normal force) Fk=μkxFn (Kinetic friction=mu times normal force) I am guessing that I have to use one of those equations. 3. The attempt at a solution Here is my small attempt. F=ma 15N=(8g)(a) a=1.875m/s^2 This is where I get stuck. First off I don't even know if the value I got for acceleration is correct and secondly where do I go from here. Do I go back to my kinematics equations to find time in part "a" and X in part "b"?
