A stationary 1.67-kg object is struck by a stick. The object experiences a horizontal force given by F = at - bt2, where t is the time in milliseconds from the instant the stick first contacts the object.
 
  If a = 1500 N/(ms) and b = 20 N/(ms)2, what is the speed of the object just after it comes away from the stick at t = 2.74 ms? A) 3.3 m/s
  B) 22 m/s
  C) 3.7 m/s
  D) 25 m/s

Question 2

A spaceship with a mass of 2.8  106 kg is traveling toward two asteroids, each with a mass of 5.0  1016 kg, which are 40 km apart. Its path is perpendicular to the line joining the asteroids and aimed at the midpoint of that line.
 
  What is the net gravitational force exerted by the asteroids on the spaceship when the spaceship is 30 km away from that midpoint? G = 6.67 x 10-11 Nm2/kg2. A) 12,000 N
  B) 8000 N
  C) 16,000 N
  D) 6200 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.
