A 16-kg mass is placed on a 25 incline and friction keeps it from sliding. The coefficient of static friction in this case is 0.574 and the coefficient of sliding friction is 0.519 . 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. 0.47 m/s2
  b. 0.47 m/s2
  c. 0.96 m/s2
  d. 0.96 m/s2
  e. 14.50 m/s2

Question 2

A 12.0-kg mass is placed on a 29.0 incline and friction keeps it from sliding. The coefficient of static friction in this case is 0.660, and the coefficient of sliding friction is 0.546 . The mass is given a shove causing it to slide down the incline. What is the frictional force while the mass is sliding?
 a. 57.0 N
  b. 102.9 N
  c. 56.2 N
  d. 67.9 N
  e. 10.5 N
