When the balanced force is applied on the ball It will roll away from the force.
<u>Explanation:</u>
- A ball lies on the floor in rest. If the balanced force is applied to
the ball, the force will push away.
- The forces would include gravity and the forces of air particles entering the ball from almost all directions.
- And the ground is exercising the force and shifting away from the impact.

KE= (1/2) mv²
So, the variables we need to include in our question would be a varable for a mass(m) of an object at some velocity(v).
My Answer:
(This is just an example question, yours can be different)
What is the Kinetic Energy experienced by an bouncy ball rolling at 7m/s (that's your velocity) across a frictionless surface that has a mass(m) of 10 grams?
Answer:
The deceleration is 
Explanation:
From the question we are told that
The height above firefighter safety net is 
The length by which the net is stretched is 
From the law of energy conservation
Where 
is the kinetic energy of the person before jumping which equal to zero(because to kinetic energy at maximum height )
and 
is the potential energy of the before jumping which is mathematically represented at
and 
is the kinetic energy of the person just before landing on the safety net which is mathematically represented at
and 
is the potential energy of the person as he lands on the safety net which has a value of zero (because it is converted to kinetic energy )
So the above equation becomes
=> 
substituting values
Applying the equation o motion
Now the final velocity is zero because the person comes to rest
So
I think you wanted to know whether the statement given is true or false. Based on this assumption, i am trying to answer the question as accurately as possible and hope that it helps. It is a true statement that amount consumed from each food group depends on their age, gender and physical activity of a person. A sportsman will consume a different amount from each food group than a normal person is a simple example.
