Balanced Forces acting on an object will not change the object's motion. Unbalanced Forces acting on an object will change the change the object's motion.

TRUE

Explanation:

The answer is true.

Balance forces acting on a body will not change the motion of the body because the body experiences no net resultant force in one direction. When any body experiences equal forces with opposite directions, the net force or the resultant force experience by the body is zero.

In case of an unbalanced forces, there is a net force acting in one direction and so it causes the body to change in its state of motion in the direction of the net force.

D.) The baseball is thrown at 50 m/s and the softball is thrown at 25 m/s.

Explanation:

mass of ball 1

mass of ball 2

now we know that if the momentum of two balls are same then we will have

so we have

so velocity of light ball must be twice the velocity of heavy ball

so correct answer will be

D.) The baseball is thrown at 50 m/s and the softball is thrown at 25 m/s.
