Question

a ball is thrown straight up from height h while a second one is dropped from h. neglect air resistance.
a) throw ball up
b) drop ball
after the balls have been released....
the one dropped has the greater acceleration
neither ball accelerates after it has been released
the one thrown up has the greater acceleration
the accelerations are the same

Explanation:

When neglecting air resistance, both balls are under the influence of gravity. The acceleration due to gravity ($g$) near the Earth's surface is constant (approximately $9.8\ m/s^2$) and acts downward on both objects, regardless of their initial velocity (the thrown ball has an initial upward velocity, the dropped ball has an initial velocity of $0$). So both balls experience the same acceleration (the acceleration due to gravity).

Answer:

the accelerations are the same
