A 12.0-kg mass is placed on a 25.0 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
  c. -0.477 m/s2
  b. 1.99 m/s2
  d. 0.477 m/s2

Question 2

A 12.0-kg mass is placed on a 25.0 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 .

 a. 55.4 N
  c. 49.7 N
  b. 107 N
  d. 61.2 N
