Question

Energy(P. E) 4,900 USED TO RAISE AN OBJECT WITH MASS OF 50 KG TO A HEIGHT (H). WHAT IS THE HEIGHT OF THE (H)?

Answer 1

Potential energy = mgh
Where m= mass , h = height , g = acceleration due to gravity
Thus, 4900 = 50*height
Height = 4900/50
= 98 m ( assuming the units are in SI system because you have not mentioned the unit of energy )

So, the height is 98m


Hope it helps you.
