Final answer:
The three scenarios that have balanced forces are: Nur ice skating in a straight line at a constant speed, Malik throwing a baseball, and Qamar resting at the top of Stone Mountain.
Step-by-step explanation:
From the given scenarios, the three scenarios that have balanced forces are:
- Nur is ice skating and glides across the ice in a straight line and a constant speed. In this case, the force acting on Nur is balanced, resulting in a constant speed.
- Malik throws a baseball from first base to second. While there is a force applied to the baseball, it does not affect its overall motion or velocity, therefore the forces are balanced.
- Qamar rests at the top of Stone Mountain and enjoys the view. When Qamar is at rest, the forces acting on him are balanced.
