List the kinematic variables and their meanings.

Kinematic vari- ables can be used to describe the state of rest or motion of a body, and these variables include the position, velocity, and acceleration of the body under investigation.

explanation:

the masses of the objects and the distance between them

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
