 3. Using the equation $v = v_0 + at \to a = \frac{(v - v_0)}{t}$, $a$ = $(50 m/s - 0 m/s)/ 6s = 8.3m/s^2$

+> An object slides until coming to a rest. It traveled 15 meters in 3 seconds. What was the object's acceleration?
+1. The problem is a kinematics problem, refer to the above formula.
+2. Acceleration is a constant
+3. Problem has two unknowns, $v_0$ and $a$, let's solve for $v_0$ first.
