C because you factor it out
Volume of a cone is 1/3 of the area of the base times the height
v=(1/3)pi*5*5*18=(1/3)pi815*15*h
h=2
The formula for the velocity, v is √2E/m
<h3>What is kinetic energy?</h3>
Kinetic energy is half the mass multiplied by the square of the speed of the object
It is written thus;
Kinetic energy = 1/ 2 × m × v²
To solve for 'v' mean that we should make 'v' the subject of formula
E = 1/ 2 mv²
E = 
cross multiply

To make 'v' the subject, we have

Thus, the formula for the velocity, v is √2E/m
