A ball is thrown up at 30m/s from the ground. What is it s maximum height?<br> How long did it take?
Rzqust [24]

<u>Answer: </u>

Maximum height reached by the ball thrown up at  30m/s is   3.06 seconds  and the height reached is  45.9 meters

<u>Explanation</u>:

Given:

Initial velocityu=30 \mathrm{m} / \mathrm{s}

To find :

maximum height =?

time taken=?

Solution:

<em>Step 1:Finding the time taken to reach the highest point</em>:

The velocity of the ball at its highest ,final velocity v=0

Using the formula,

v=u+a t

Where a is acceleration due to gravity.Its value is-9.8 m / s^{2}

Substituting the values:  

0=30+(-9.8) t

-30=(-9.8) t

t=\frac{30}{9.8}

t=3.06 \mathrm{seconds}

<em>Step 2: finding the highest point </em>

Using the formula

v^{2}-u^{2}=2 a s

where

s is the maximum highest.

Substituting values

0^{2}-(30)^{2}=2(-9.8) s

0-900=(-19.6) s

-900=(-19.6) s

s=\frac{900}{19.6}

s=45.9 \text { meters }

Result:

Thus the maximum height reached is 45.9 meters in 3.06 seconds

What is Laminar flow??​
barxatty [35]

Answer:

Explanation:

Laminar Flow is a very important topic discussed in physics in the subject of fluid dynamics. Basically, it explains how fluid particles behave at lower velocities. In such cases and when the viscosity of the fluid is low, the fluid particles flow smoothly in perfectly perpendicular layers that do not collide or cross each other. Unlike turbulent flow, which is the opposite. An example of Laminar flow can be seen when you open up a water hose with little pressure, the water simply flows out of the hose and looks very clear and smooth.
