A tennis ball is dropped from the top of a tall building. a second tennis ball is thrown down from the same building make a statement about the acceleration of each tennis ball.

A) The first ball falls with a greater acceleration

B) The second ball falls with a greater acceleration.

C) they both are with the same acceleration because they started from the same height.

D) they both are the same acceleration because they are in free fall.

E) more information is required

Respuesta :

The two balls have the same acceleration because they are in free fall.

The two balls projected downwards from the top of the build are influenced by gravity. Both ball experience free fall due to gravity.

The equation of motion of the two ball is given as;

v² = u² + 2gh

where;

  • v is the final velocity of each ball
  • u is the initial velocity of each ball
  • h is the distance traveled by each ball
  • g is acceleration due to gravity = 9.8 m/s²

Thus, we can conclude that the two balls have the same acceleration because they are in free fall.
