If an object moves, stops, changes speed, or even changes direction, then that condition represents the unbalanced force condition.
Unbalanced Force:
The unbalanced force is the magnitude of the net force that tends to cause the motion of objects. It is nothing but the greater amount of force to be applied to the object to displace the object in either direction.
If an object is moving, stopping, changing the speed, or changing the direction, then such activities directly show that the object is changing its state of motion. And the change in the motion is only caused when there is some magnitude of force associated with it.
- When the magnitude of forces applied on an object such that one force is greater than another in a specific direction, then such forces are known as unbalanced forces.
- Unbalanced forces cause motion, which means a body can move, stop or even can change its direction due to the unbalanced force.
Thus, we can conclude that if an object moves, stops, changes speed, or even changes direction, then that condition represents the unbalanced force condition.

Answer:
Explanation:
Since the package remains in contact with the car's seat, the package's speed is equal to the car's speed. At the top on the mountain the package's centripetal force must be equal to its weight:
The centripetal force is defined as:
Here v is the linear speed of the object and r is the radius of curvature. We need to convert the linear speed to 
:
Now, we calculate r:
No becuase the simplified case of constant speed, use the formula:
<span>distance = speed x time</span>
Answer:
The velocity when the ball hits the ground is obtained using v2. 2 = v1. 2 + 2 g Dy with v1=0 and Dy=h. Thus solving for v2 yields 17.1 m/s v2 = 2 g h =.
