Answer:
Height, h = 10.20 meters
Explanation:
It is given that,
Mass of the object, m = 3 kg
Energy of object, E = 300 J
Let it will moved to a height of h. The energy possessed by it is called gravitational potential energy. It is given by :
h = 10.20 meters
So, the object will move to height of 10.20 meters. Hence, this is the required solution.
Distance to the moon = 4×m.
1 m = 3.28 ft
Distance to the moon in ft = 4××3.28 ft
= 13.12 ×ft
1 fathom = 6 ft
Hence, distance to the moon in fathom
= ×
≈ 2× fathom
