Answer:
Height, h = 1.2 meters
Step-by-step explanation:
It is given that,
Mass of an object, m = 6 kg
Gravitational potential energy, E = 70.56 J
It is lifted off a ground to a height h. We need to find its height. It can be determined using the expression for the potential energy i.e.
E = m g h
g = acceleration due to gravity
h = 1.2 meters
Hence, it is lifted off the ground to a height of 1.2 meters.
