1. these students are playing tug of war during field day. explain if it is a balanced or unbalanced force and how you know.
2. what is the net force and in which direction would the force be moving if needed?

Explanation:

Step1: Calculate the velocity

Velocity is a vector quantity that has both magnitude and direction. The formula for velocity is \(v=\frac{d}{t}\), where \(d\) is the displacement and \(t\) is the time.
Given \(d = 3000\) km and \(t=5\) hours.
Substitute the values into the formula: \(v=\frac{3000}{5}=600\) km/h.
Since the plane is traveling from New York to California (west - direction), the velocity is \(600\) km/h west.

Answer:

c. \(600\) km/h west
