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

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
