A man is sitting on a 20 m height building and his mass is 50 kg. Calculate the mechanical energy.
1 answer:
Answer:
9810 Joules
Explanation:
Given parameters are,
m = 50 kg
h = 20m
the man is not moving, therefore, K. E = 0
The formula of mechanical energy
M.E = 1/2 mv2 + mgh
Since K.E is 0, the equation becomes,
M.E = mgh
M.E = 50 ×9.81 ×20
M.E = 9810 J
Hence the mechanical energy is 9810 Joules
