Hi!
The answer would be 22.5m
<h3>Explanation</h3>
To calculate the distance the ball travels, you would need to apply the following formula from the equations of motion for an accelerating object:
2as = v^2 - u^2
Where a is acceleration due to gravity, 9.8m/s^2
s is the distance traveled by the object (height of ball in this case)
v is the final velocity, which we know will be zero at the point where the ball reaches maximum height.
u is the initial velocity, which is known to us as 21m/s
Rearranging the equation to solve for the height:
s = (v^2 - u^2 ) / 2a
s = ( 0^2 - 21^2 ) / 2(-9.8)
s = - 441/ - 19.6
s = 22.5m
<em>Note: since gravity is acting against the object's motion, it will be negative </em>
<em>Hope this helps!</em>
Its axis is tilted on the side.
If the domains of ferromagnetic are oriented randomly, THE MATERIAL IS NON MAGNETIC.
The magnetic properties exhibited by some elements is due to the motion of their electrons at the atomic level. Ferromagnetic materials have different domains, when these domain are oriented randomly, they cancel one another out and the material become non magnetic.
