Question

A bag of wheat weighs 20 kg. What will be the height to which it should be raised so that its potential energy is 1000 joules.
Given: g= 10ms^-2
​

Answer 1

Answer:

Explanation:

potential energy=m*g*h

1000j=20*10*h

1000/200=h

h=5m

Answer 2

Answer:

Explanation:

M=20kg

W=1000J

G=10ms^-2

We know that

KE=PE

So

PE

W=mgh

Let H=height

1000=20*10*h

1000/200=h

5m=h
