  what is the magnitude of its initial acceleration if the only forces acting on it are the gravitational forces due to the other two masses? (G = 6.67  10-11 N  m2/kg2)
  A) 3.7  10-8 m/s2
  B) 2.5  10-8 m/s2
  C) 1.9  10-8 m/s2
  D) 4.2  10-8 m/s2
  E) 6.4  10-8 m/s2

Question 2

A 0.140 kg baseball is thrown horizontally with a velocity of 28.9 m/s. It is struck with a constant horizontal force that lasts for 1.85 ms, which results in a velocity of 37.0 m/s in the opposite direction.
 
  What was the magnitude of the horizontal force? A) 0.613 kN
  B) 2.19 kN
  C) 2.80 kN
