Answer 1

$\Huge \sf \mathbb \color{Yellow}\underline{\colorbox{pink}{✨Answer✨}}$

FORMULA USED

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

POTENTIAL ENERGY AT POINT A,

HEIGHT = 1 + 1.5 m = 2.5 m

G = 10 m/s

MASS = 5 kg

PE = 2.5 X 10 X 5 = 125 joule

POTENTIAL ENERGY AT POINT B,

HEIGHT = 1.5 m

G = 10m/s

MASS = 5 KG

PE = 1.5 X 10 X 5 = 75 JOULE

POTENTIAL ENERGY AT POINT C,

HEIGHT = 0

G = 10m/s

MASS = 5 KG

PE = 0 X 10 X 5 = 0 JOULE
