Question

4. A box containing some material, weighs 200 kg. It
was raised to certain height so that its potential
energy becomes 9800 J. Calculate the height to
which it was raised.
​

Answer 1

Answer:

Potential energy =m×g×h (here m=200kg, g=9.8ms

−2

, potential energy =9800 joule)

9800J=200Kg×9.8ms

−2

×h

h=

200×9.8

9800

h=5m

Thus, the bag of wheat should be raised to a height of 5m.
