you hurriedly climb the 5 meter staircase just to get to the second floor of the building in three second. how much power you spend in climbing the stairs? how mush power you spend in climbing the stairs?
Answers
Gravity is a physical connection between space and matter that is precisely described by Einstein's 1915 geometric theory of gravity known as general relativity. Put simply, that theory says, "Space acts on matter, telling it how to move. In turn, matter reacts back on space, telling it how to curve."
Given - Height : 5 meter
Time : 3 seconds
Find - Power
Solution - Power can be calculated by the formula work done per unit time. Further work done can be calculated as product of mass, acceleration due to gravity and height.
The question mentions "you" as the person so taking my mass as 50 kilogram. Taking acceleration due to gravity as 10 m/s².
Keeping the values in formula -
Power = 50*10*5/3
Power = 833 Watt
Hence, power I spend in climbing the stairs is 833 Watt.
