Answer:
MGH
Explanation:
Initial Energy of the body
=K.E+P.E
KEi
=0,PEi
=mgh
Final Energy KEf +PEf
PEf
=0
Energy is conserved
Final Energy
= Initial Energy
KEf
=PEi
=mgh

Answer:
Where m is mass of the object, v is its velocity, g is acceleration due to gravity and h is height.
Thus mass being unchanging and g approximated to 9.8, the point where h = 0.051 × v × v will be where kinetic energy is equal to potential energy. This value is obtained by equating KE to PE and solving for ‘h’.
