TO FIND THE HEIGHT OF BUILDING BY DROPPING STONES FROM top 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 edifice by displace rocknrolls from prime of building Materials required- 5 Pebbles or Stones A Stopwatch Theory The height of the building is the pop off 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 initial velocity becomes zero, i.e. [pic] [pic]----------- 2 Where, [pic] We find t as the second-rate of sentence taken by the collierys to reach the ground. Precautions 1. The air may resist the motion of locomote objects 2. The clipping taken by the careen to reach the ground may not be accurate. 3. The acceleration due to gloominess may not be exact. Procedu re 1. Five stones or pebbles are dropped from the top of the base. 2. The time they took to reach the ground was noted development a stopwatch. They were as follows: 1st stone (t1):1 2nd stone (t2):1.5 third 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 multiplication by the total number of stones: [pic] [pic] [pic] [pic] 4. Then the height of the house was calculated employ 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 indispensability to aim a full essay, order it on our website: BestEssayCheap.com
