Answer:
Option D
Explanation:
The kinetic energy of a track star is given by the expression , where m is the mass of track star and v is the velocity of track star.
The potential energy is given by the expression mgh , where h is the height of track star and g is acceleration due to gravity value.
By energy conservation theory, energy can neither be created or destroyed.
So a running track stars kinetic energy is converted to potential energy when he jumps.
= mgh
h ∝
So height reached increases when velocity of speed star increases.
So the answer is the kinetic energy before the jump is converted to potential during the jump.
