Answer:
Explanation:
My speed after the interaction will depend upon the impulse the ball will make on me . Now impulse can be expressed as follows
Impulse = change in momentum
change in momentum in the ball will be maximum when the ball bounces back with the same velocity which can be shown as follows
change in momentum = mv - ( - mv ) = 2mv
So when ball is bounced back with same velocity , it suffers greatest impulse from my hand . In return , it reacts with the same impulse on my hand pushing me with greatest impulse according to third law of motion. this maximizes my speed after the interaction.

,A object of mass
at the surface of earth experiences a force
</h2>
Explanation:
Let 
be the mass of earth.
Let 
be the radius of earth.
Let 
be the universal gravitational constant.
Given,
Let 
be the acceleration due to gravity.
Then,
A object of mass at the surface of earth experiences a force
Answer:
Balanced forces do not result in any change in motion. forces: forces applied to an object in opposite directions that are not equal in size. Unbalanced forces result in a change in motion.
