A mass M slides upward along a rough plane surface inclined at an angle Theta (Θ) = 0.3 radians to the horizontal. Initially, the mass has a speed V_0 = 3.81 m/s before it slides a distance L = 1.0 m up the incline. After sliding this distance, the new speed of the mass is V_0/4 measured in m/s. What is the acceleration of the sliding mass? (Positive denotes acceleration up the incline; negative denotes acceleration down the incline.)
