Question

The magnitude of the velocity of the stone as it goes downwards ? explain? a. is increasing b. is decreasing c. remains constant d. cannot be determined

Answer 1

Given:

A stone is dropped from a height.

To find:

Variation of its magnitude of Velocity

Calculation:

Let's assume that the stone has been released from a height h :

So, its initial velocity is zero , let final velocity be v;

Applying first Equation of Kinematics :

$v = u + at$

$= > v = u + gt$

Since , g and t are positive values , hence:

$\boxed{v > u}$

So , Velocity of stone increases
