Ball A is thrown in a horizontal x-direction from a certain height. Ball B is dropped at the same time and from the same height. Which of the following statements is true about Balls A and B? (Neglect Air Resistance}

Respuesta :

Answer:

Both balls hit the ground simultaneously

Explanation:

LetĀ“s call bā‚ Ā ( the ball dropped ) the equation for a free fall movement is, tacking as the origin of coordinates Ā the level from which it was dropped

V = g*t Ā ( since Vā‚€ initial velocity is 0 )

In the case of projectile movement the equation for Vx and Vy (these speeds are independent)

are:

Vx = Vā‚€x Ā  Ā  Ā (constant) Ā  Ā and Vy = Voy + g*t Ā 

Vy = Vā‚€ * sin 0ā° + g*t Ā  Ā  Ā Vy = 0 + g*t

As we can see V is the same in both cases then the balls hit the ground simultaneously
