Two children are bouncing small rubber balls. one child simply drops a ball. at the same time, the second child throws a ball downward so that it has an initial speed of 10 m/s. what is the acceleration of each ball while in motion?

The acceleration of each ball while in motion is acceleration due to gravity, that is 9.81 m/s²

Explanation:

Here one child simply drops a ball. At the same time, the second child throws a ball downward so that it has an initial speed of 10 m/s.

In first case acceleration on the ball is acceleration due to gravity,

In second case also acceleration on the ball is acceleration due to gravity,

Only gravitational force is acting on both cases so their acceleration is acceleration due to gravity.

The acceleration of each ball while in motion is acceleration due to gravity, that is 9.81 m/s²

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
