What is "in the formula vy = ayt?

The formula vy = ayt represents the relationship between the vertical component of an object's velocity (vy), the acceleration of the object (a), and the time (t) it has been accelerating in a particular direction.

In this formula, vy is the final vertical velocity of the object, a is the acceleration in the vertical direction, and t is the time for which the object has been accelerating vertically.

This formula is derived from the equation of motion in a straight line, which relates the displacement, initial velocity, final velocity, acceleration, and time.

Using this formula, we can calculate the final vertical velocity of an object after accelerating in the vertical direction for a certain amount of time under a constant acceleration.
