The rate at which the height of the water in this cylindrical tank is increasing is 26.18 m/mn.
<h3>How to calculate the volume of a cylinder?</h3>
Mathematically, the volume of a cylindrical tank can be calculated by using this formula:
V = πr²h
Where:
Differentiating with respect to h, we have:
dV/dt = πr²(dh/dt)
3 = 3.142 × 5² × dh/dt
3 = 78.55dh/dt
dh/dt = 78.55/3
dh/dt = 26.18 m/mn.

Assuming a student pushes a 51. 5 kilogram bookshelf across a smooth floor with a net force of 67 n the acceleration is 1.30m/s².
<h3>Acceleration</h3>
Using this formula
Acceleration= Net force/Mass of bookshelf
Where:
Mass of bookshelf =51.5 kilogram
Net force =67 Newton
Let plug in the formula
Acceleration=67n/51.5 kilogram
Acceleration=1.30 m/s²
Inconclusion the acceleration is 1.30m/s².
