Question

if you apply 1joule of energy to lift a book of 0.5 kg how high it will rise

Answer 1

hola mate .......here is your answer....


we know that , potential energy = mgh

here work done is equal to energy consumed....so we take potential energy is equal to work done...

so potential energy = 1 joule.

1 joule = mgh = 0.5 × 9.8 × h = 4.9 h

so ,. h = 1 ÷ ( 4.9 ) = 0.20 metre

so height to which it will be raised is 0.20 m
