A ball is dropped from the top of a tall building. At the same instant, a second ball is thrown upward from the ground level. When the two balls pass one another, one on the way up, the other on the way down, compare the magnitudes of their acceleration:

a. The acceleration changes during the motion, so you cannot predict the exact value when the two balls pass each other.
b. The acceleration of both balls is the same.
c. The acceleration of the ball thrown upward is greater.
d. The accelerations are in opposite directions.
e. The acceleration of the dropped ball is greater.

Respuesta :

Answer:B

Explanation:

For the ball dropped From a tall ball building the direction of acceleration is downward and its magnitude is [tex]9.8 m/s^2[/tex]

For the ball thrown upward towards the dropped ball the direction and magnitude of acceleration is same i.e. downwards as gravity always acting downward with constant magnitude.

Thus option B is correct

In this case, the acceleration of both balls is the same (Option B).

What is acceleration?

Acceleration is a physical property to measure the movement of an object in a given period of time.

  • Acceleration can be estimated as a change in velocity over the change in time (.e.g., meters per second squared).

  • The conventionally used unit of measurement of the acceleration is meter per second squared.

In conclusion, in this case, the acceleration of both balls is the same (Option B).
