Mass of the body=2kg
Height lifted=10m
Let is takeg=10m/s^2
Potential energy=m*g*h
=2*10*10
=200 joules
Potential energy=Kinetic energy
(law of conservation of energy)
Kinetic energy=200 joules
Height lifted=10m
Let is takeg=10m/s^2
Potential energy=m*g*h
=2*10*10
=200 joules
Potential energy=Kinetic energy
(law of conservation of energy)
Kinetic energy=200 joules
