Answer: a pattern in nature observed over and over

Explanation:

A scientific law can be define as statement which either describes or predict the natural phenomena. The information given in the scientific law is verified by the experimental procedures and observations which are done under conditions which are tried to mimic the natural system. It can be used to describe the cause of a natural phenomena, duration of natural phenomena  and conditions necessary for the occurrence of natural phenomena and also gives information why and how a natural phenomena repeat itself.

Ball is dropped from the height H the total distance covered in last second of its motion is equal to distance covered in first
Alik [6]

\rm{\gray{\underline{\underline{\blue{GIVEN:-}}}}}

  • A ball is dropped from a height = H

  • The total distance covered in last second of its motion is equal to the distance covered in first 3 second .

\rm{\gray{\underline{\underline{\blue{TO\:FIND:-}}}}}

  • The height of the journey .

\rm{\gray{\underline{\underline{\blue{SOLUTION:-}}}}}

We have know that,

\green\bigstar\:\rm{\gray{\overbrace{\underbrace{\red{S\:=\:ut\:+\:\dfrac{1}{2}\:at^2\:}}}}}

Where,

  • S = Distance .

  • u = initial velocity = 0m/s

  • t = time = 3s

  • a = acceleration

[Note :- Here, acceleration is ‛acceleration due to gravity’ .]

  • a = 10m/s^2

=> S = 1/2 × 10 × (3)^2

=> S = 5 × 9

=> S = <u>4</u><u>5</u><u>m</u> -----(1)

✒ If the ball takes ‛n’ second to fall the ground, then distance covered in nth second is,

\green\bigstar\:\rm{\gray{\overbrace{\underbrace{\red{S_n\:=\:u\:+\:\dfrac{g}{2}\:(2n\:-\:1)\:}}}}}

=> Sn = 0 + 10/2 (2 × n - 1)

=> Sn = 5 (2n - 1)

=> Sn = 10n - 5 -----(2)

Therefore,

  • 10n - 5 = 45

=> 10n = 45 + 5

=> n = 50/10

=> n = <u>5</u>

Now put the value of ‛n = 5’ in equation(2), we get

=> Sn = 10 × 5 - 5

=> Sn = 50 - 5

=> <u>Sn</u><u> </u><u>=</u><u> </u><u>4</u><u>5</u><u>m</u>

\rm{\pink{\therefore}} The height of the journey is “ <u>4</u><u>5</u><u>m</u> ” .
