Q. A 75-kg piano is hoisted on a crane and delivered through the window of a 6 storey apartment (20 meters above the ground). What is the potential energy of the piano?

$\Huge \sf \mathbb \color{Yellow}\underline{\colorbox{pink}{✨Answer✨}}</p><p>$

FORMULA USED

• POTENTIAL ENERGY = MGH
• M =MASS
• G = ACCELERATION DUE TO GRAVITY
• H = HEIGHT ABOVE THE GROUND

GIVEN,

MASS = 75 KG

G = 10m/s

H = 20 m

SO, PE = 75 X 20 X 10 = 15000 JOULE
