A javelin thrower standing at rest holds the center of the javelin behind her head, then accelerates it through a distance of 75 cm as she throws. She releases the 620 g javelin 2.0 m above the ground traveling at an angle of 32 above the horizontal. Top-rated javelin throwers do throw at about a 30 angle, not the 45 you might have expected, because the biomechanics of the arm allow them to throw the javelin much faster at 32 than they would be able to at 45. In this throw, the javelin hits the ground 58 m away.

What was the acceleration of the javelin during the throw? Assume that it has a constant acceleration. Express your answer with the appropriate units.
