Question

16. A body of mass 60 kg is raised to a height of 15 m above the ground. Calculate the potential energy
stored in the body.( take g=9.8 ms)
​

Answer 1

Answer:

75 is the correct answer

Answer 2

Answer:

Explanation:

Given :

• Mass of a body (m) = 60 kg
• Height (h) = 15 m
• Acceleration due to gravity (g) = 9.8 m/s²

To Find :

• The potential energy stored in the body.

Solution :

Formula of "Potential energy" is given as;

• P.E = mgh

=> P.E = 60 × 9.8 × 15

=> P.E = 60 × 147

=> P.E = 8820 J

Hence :

The potential energy stored in the body is 8820 J.

• W = F × s
• K.E = ¹/2 × mv²
• M.E = P.E + K.E
