TO FIND THE HEIGHT OF BUILDING BY DROPPING STONES FROM go by 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 create by displace rocknrolls from prime of building Materials required- 5 Pebbles or Stones A Stopwatch Theory The height of the building is the slip by 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 medium of sentence taken by the collierys to reach the ground. Precautions 1. The air may resist the motion of locomote objects 2. The epoch taken by the muffin 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 cartridge holder 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 dwelling 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, bar the time taken by them to reach the ground, noting their average time an d using the formula h=1/2 at2.If you fate t! o aim a full essay, order it on our website: OrderEssay.net
