Question

If you apply 1 joule of energy to lift a book of 0.5 kg how high will it rise (g=10m/s)

Answer 1

Answer:

It will rise by 0.2 meter

Explanation:

Force=Mass ×Acceleration due to gravity

Force=0.5kg ×10m/s2(this means 10 meter square)

Force=5Newton

We know,

Work=Force×Displacement

1 Joule=5N×D

D=1Joule÷5 N

D=0.2 meter
