The magnitude of the acceleration is equal to 31.5
<u>Given the following data:</u>
To determine the magnitude of the acceleration:
In Science, the acceleration of a particle in a <u>circle</u> or circular track is known as centripetal acceleration.
<h3>How to calculate
centripetal acceleration.</h3>
Mathematically, centripetal acceleration is given by this formula:
Substituting the given parameters into the formula, we have;
Centripetal acceleration = 31.5

Answer:
m/min
Explanation:
You have to use the volume of a cone, which is:
where r is the radius of the base and h is the height.
In this case, r=5 and h=10. The radius can be written as r=h/2
Replacing it in the equation:
(I)
The rate of the volume is the derivate of volume respect time, therefore you have to perform the implicit differentiation of the previous equation and equal the result to 3.14 m³/min
Replacing dV/dt= 3.14, h=7.5 and solving for dh/dt, which represents how fast the level is rising:
Multiplying by 16/225π both sides:
m/min
