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
