Three identical 50-kg balls are held at the corners of an equilateral triangle, 30 cm on each side. If one of the balls is released,
 
  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
  D) 4.99 kN
