Question

The change in energy of a body while moving from ground floor to the tenth floor of a building is 1000J. If mass of the body is 10kg and acceleration due to gravity is 10m/s², calculate the height of the tenth floor. BATA DO Yrr KOI PLZ​

Answer 1

A N S W E R :

Given,

Mass of object m=10kg.

Height h=6m.

Acceleration due to gravity g=9.8m/s

2

Potential Energy of object P.E=m×g×h

⇒mgh=10×9.8×6=98×6

=588J

Energy possessed by the object is 588Joule.
