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 . The mass is given a shove causing it to slide down the incline. What is the frictional force while the mass is sliding?
 a. 55.4 N
  c. 49.7 N
  b. 107 N
  d. 61.2 N

It is believed that the Incas used anesthesia. Evidence supports the theory that shamans chewed cocoa leaves and drilled holes into the heads of patients (letting evil spirits escape), spitting into the wounds they made. The mixture of cocaine, saliva, and resin numbed the site enough to allow hours of drilling.
