Question

Calculate the energy possesed by a body of mass 450gm lufted to a height of 2500cm.given, g=10m/s^2

Answer 1

Answer:

The energy possessed by the body is 11.25 Joules.

Explanation:

(The energy possessed by this object should be Potential Energy because this body is at a height and the energy possessed due to height is Potential Energy.)

$m=450g=0.45kg$

$g=10m/{s}^2$

$h=2500cm=25m$

$P.E.=mgh$

$P.E.=0.45*10*2.5$

$P.E.=4.5*2.5$

$P.E.=11.25J$
