Answer:
40.83Kg
Explanation:
Data obtained from the question include:
P.E (potential energy) = 400100J
g (acceleration due to gravity) = 9.8m/s2
h (height) = 1000m
m (mass) =?
Potential energy has a formula:
P.E = mgh.
With the above formula, the mass can be obtained as follow:
P.E = mgh
m = P.E /gh
m = 400100/ 9.8x1000
m = 40.83Kg
