A ball is thrown straight up, when it reaches the maximum height x, a second identical ball is thrown up with the same initial velocity as the first one. Where will these balls meet.
To determine where the two balls will meet, we need to understand their trajectories.
First, let's consider the motion of the first ball. As it is thrown straight up, it experiences the force of gravity, causing it to slow down until it finally reaches its maximum height and starts coming back down. The height at which it reaches its maximum is denoted as x.
Now, let's consider the motion of the second ball. It is also thrown straight up with the same initial velocity as the first ball. Since the balls are identical, their trajectories will be symmetrical. Therefore, the second ball will follow the same path as the first ball, just in reverse.
When two objects are thrown up with the same initial velocity, they will meet at the point where their paths intersect. In this case, since the balls are symmetrical, they will meet at the same height x.
Therefore, the two balls will meet at the maximum height x.
