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"?
