Answer 2

★ Question Given :

• To what height should a body of mass 5 kg be raised so that its potential energy is 490 J? [g = 9.8 m/s2]

★ Required Solution :

✫ Value Given to us :

• ⇢ Mass of Man = 5 kg

• ⇢ Potential energy = 490 J

• ⇢ g Value = 9.8 m/s²

✫ Formula Used Here :

• ⇢ Potential Energy = mgh

★ Where :

• ⇢ m = Mass

• ⇢ g = Accelerating due to gravity

• ⇢ h = Height

✫ Putting Value in Formula :

• ⇢ Potential energy = mgh

• ⇢ 490 = 5 × 9.8 × h

• ⇢ h = 10 m

✰ Height is 10 m ✰
