Question

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}

Answer 1

Both balls hit the ground simultaneously

Step-by-step explanation:

Let´s call b₁ ( the ball dropped ) the equation for a free fall movement is, tacking as the origin of coordinates the level from which it was dropped

V = g*t ( since V₀ initial velocity is 0 )

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

are:

Vx = V₀x (constant) and Vy = Voy + g*t

Vy = V₀ * sin 0⁰ + g*t Vy = 0 + g*t

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