A 12.0-kg mass is placed on a 25.0 $\degree$ incline and friction keeps it from sliding. The coefficient of static friction in this case is 0.580 and the coefficient of sliding friction is 0.520. The mass is given a shove causing it to slide down the incline. Taking down the incline as positive, what is the acceleration of the mass while it is sliding? A) "-1.99 m/s²" B) "1.99 m/s²" C) "-0.477 m/s²" D) "0.477 m/s²"
