A Projectile is any object that moves under the influence of gravity and momentum only.

Examples are :- a thrown ball, a fired bullet, a kicked ball, thrown javelin, etc.

Given that the ball was thrown vertically upward from the height of 61.9 m.

So that the velocity can be determined by :-

u = $\sqrt{\frac{2H}{g} }$

Where: u is the velocity of the object, H is the height and g is the gravitational force on the object.

Given that: H = 61.9 m and g = 10 m/ $s^{2}$

Then :+

u = $\sqrt{\frac{2*61.9}{10} }$

= $\sqrt{\frac{123.8}{10} }$

u = 3.5185

The velocity of the ball is 3.52 m/s.
