Well, we finally got to the acceleration topic, which, as you know, is the change in speed over time.

Condition:

The second body was thrown vertically upward next to the first one after t with the same speed v. How long after throwing the second body and at which height h the two bodies will collide?

Solution:

Distance traveled equation

For the first body

For the second body

Accordingly, when they meet, their coordinates will coincide, i.e.

,

from which

After finding time, substitute it in any formula for the distance and find h

Gravitational acceleration is assumed to equal 9.8 m/s2
