Jody will have strong bones and show muscle hypertrophy.

Explanation:

Long distance running practiced regularly helps in increasing the strength of bones. Muscular hypertrophy is the increase in mass of skeletal muscles due to the increase in the size of myofibrils or increase in muscle glycogen storage. Strength training exercises performed regularly induce muscular hypertrophy.

During strength training exercises muscles undergo contraction and repeated contraction breaks muscle fibres. New muscle fibres are added as a means of repair and this happens at the relaxing phase of muscles. More muscle fibres are added to compensate the damage and thus muscle mass increases.

it breaks and dirupture other materials and other sencews from the bottom

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
