Question

Find the energy possessed by an object of mass 10 kg when it is at a height of 6 cm above the ground.​

Answer 1

Answer:

• $Energy\:possessed=6\:J$

Explanation:

$Given:-$

• Mass of body = 10 kg
• Height = 6 cm = 6/100 = 0.06m

$ToFind:-$

• Energy possessed

$Solution :-$

$\implies \:\:Kinetic \: Energy = \frac{1}{2} m {v}^{2}$

$\implies \:\: \frac{1}{2} \times 10 \times {0}^{2}$

$\implies \:\:0 \: J. . . . . (1)$

$\implies \:\:Potential\: Energy =mgh$

$\implies \:\:10 \times 10 \times 0.06$

$\implies \:\:6 \: J . . . . . (2)$

$Adding \: (1) \: and \: (2)$

$\implies \:\:Energy \: possessed = K.E + P.E$

$\implies \:\:0 + 6$

$\implies \:\:6 \: J$
