A 0.25 kg ball is dropped from a 30 meter building. At the same time, a 2 kg ball is thrown downward with a 50 N force. Neglecting air resistance and after it is thrown, the ball will have an acceleration (a) equal to 8 times that of the dropped ball. (b) equal to 1/8 of that of the dropped ball. (c) equal to that of the dropped ball. (d) always larger than, but not always 8 times larger than, that of the dropped ball. (e) always smaller than, but not always 8 times smaller than, that of the dropped ball.

(c) equal to that of the dropped ball.

Explanation:

In the case of the thrown ball at the time of thrown there for only force maybe force can act on it after thrown there is no longer applied force and only it has the value of the acceleration equal to gravity.

Both the ball is having the same acceleration and that is equal to the acceleration due to gravity. We know that acceleration due to gravity is equal to 9.81 m/s².

So we can say that the answer is C.
