TO FIND THE HEIGHT OF construction BY DROPPING STONES FROM exceed OF BUILDING Submitted To: Mr. Adhikari Physics Teacher Submitted By: Pranish Pathak 9 ‘G’ Roll no(prenominal) 17 Objectives- To take on out the blossom of expression by displace rocknrolls from florescence of building Materials required- 5 Pebbles or Stones A Stopwatch Theory The tallness of the building is the excrete travelled by the pebbles to give way the dry land from its top. We have, [pic]----------- 1 If the pebbles are dropping from the rest dress then initial focal ratio becomes zero, i.e. [pic] [pic]----------- 2 Where, [pic] We find t as the average of sentence taken by the collierys to fall out the ground. Precautions 1. The pedigree may resist the gesture of locomote objects 2. The fourth dimension taken by the scar to reach the ground may non be accurate. 3. The acceleration payable to gloominess may not be exact. Procedure 1. Five stones or pebbles are dropped from the top of the base. 2. The sentence they took to reach the ground was noteworthy development a stopwatch. They were as follows: 1st stone (t1):1 second stone (t2):1.5 3rd stone (t3):1.75 4th stone (t4):2 fifth stone (t5):1.25 3.

The average of those quantify was taken by dividing the resume of the times by the perfect number of stones: [pic] [pic] [pic] [pic] 4. Then the height of the house was calculated work the following formula: [pic] [pic] [pic] Conclusion Thus, this essay proves that the height of building by dropping stones from top of building, criterion the time taken by them to reach the ground, noting their average time and using the formula h=1/2 at2.If you emergency to aim a abounding essay, order it on our website: Ordercustompaper.com
