Question

A bag of wheat weighs 300kg to what height should it be raised so that its potential energy may be 10000 joules , gravity = 9.8m/s2​

Answer 1

Answer:

3.40km

3.4013605442fu

Answer 2

Given :

• Weight = 300 kg

• Potential Energy = 10000 J

• Gravity = 9.8 m/s²

To Find :

• We have to find height

Solution :

As we know that,

• Potential Energy = mgh
• Weight = mg

Formula to be used here :

• P.E = m × g × h

Substituting the values,

• ➞ P.E = m × g × h

• ➞ 10000 = 300 × 9.8 × h

• ➞ h = 10000/300 × 9.8

• ➞ h = 10000/2940

• ➞ h = 3.40136

• ➞ h = 3.4m

Hence, Bag is placed at the height of 3.4m
