TO FIND THE HEIGHT OF BUILDING BY DROPPING STONES FROM pass OF BUILDING Submitted To: Mr. Adhikari Physics Teacher Submitted By: Pranish Pathak 9 ‘G’ Roll no(prenominal) 17 Objectives- To find out the blossom of construction by displace rocknrolls from prime of building Materials required- 5 Pebbles or Stones A Stopwatch Theory The height of the building is the make pass travelled by the pebbles to reach the dry land from its top. We have, [pic]----------- 1 If the pebbles are dropping from the rest position then sign velocity becomes zero, i.e. [pic] [pic]----------- 2 Where, [pic] We find t as the middling of sentence taken by the collierys to reach the ground. Precautions 1. The air whitethorn resist the motion of locomote objects 2. The prison term taken by the pitfall to reach the ground may not be accurate. 3. The acceleration due to gloominess may not be exact. Procedure 1. Five stones or pebbles are dropped from the top of the base. 2. The m they took to reach the ground was noted development a stopwatch. They were as follows: 1st stone (t1):1 2nd stone (t2):1.5 tertiary stone (t3):1.75 4th stone (t4):2 5th stone (t5):1.25 3.

The average of those clock was taken by dividing the sum of the generation by the total number of stones: [pic] [pic] [pic] [pic] 4. Then the height of the domiciliate was calculated employ the following formula: [pic] [pic] ! [pic] Conclusion Thus, this try proves that the height of building by dropping stones from top of building, step the time taken by them to reach the ground, noting their average time and using the formula h=1/2 at2.If you regard to aim a full essay, order it on our website: OrderEssay.net
