A steady horizontal force lasting for 2.10 s gives a 1.25 kg object an acceleration of 3.20 m/s2 on a frictionless table. What impulse does this force give to the object?
 
  A) 25.7 kg m/s
  B) 10.9 kg m/s
  C) 8.40 kg m/s
  D) 4.00 kg m/s
  E) 2.63 kg m/s

Question 2

On planet X, the absolute pressure at a depth of 2.00 m below the surface of a liquid nitrogen lake is 5.00  105 N/m2. At a depth 5.00 m below the surface, the absolute pressure is 8.00  105 N/m2. The density of liquid nitrogen is 808 kg/m3.
 
  (a) What is the atmospheric pressure on planet X?
  (b) What is the acceleration due to gravity on planet X?

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.
