What is the correct interpretation of this diagram 1. since the unbalanced force is at the top, the object will move down. 2. since three forces are balanced, the object will not change position. 3. since the unbalanced forces an upward force, the object will move upward. 4. since the unbalanced force is a downward force, the object will move down.

3 because 450 N is a bigger force than the rest so it will move up

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
