Final answer to the problem below?

58. III A javelin thrower standing at rest holds the center of the javelin
BIO behind her head, then accelerates it through a distance of 70 cm as
she throws. She releases the javelin 2.0 m above the ground
traveling at an angle of 30° 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 30° than they would be able to at
45°. In this throw, the javelin hits the ground 62 m away. What was
the acceleration of the javelin during the throw? Assume that it has
a constant acceleration.
