Question

what is the effect of air resistance on the box as it moves forward at time 4? energy transfers and contact forces in the launcher, cart, box, and track system the box speeds up because air pushes it forward the box slows down because it collides with the air and causes the air to move the boxs speed stays the same the box gains energy from the track

Explanation:

Air resistance is a force that opposes the motion of an object. When the box moves forward, it collides with air molecules. According to Newton's third law, the air exerts a backward - acting force on the box. This force does work against the motion of the box, converting some of the box's kinetic energy into other forms (such as thermal energy due to the motion of air molecules). As a result, the box's kinetic energy decreases, and since kinetic energy \(K = \frac{1}{2}mv^{2}\) (where \(m\) is the mass of the box and \(v\) is its speed), its speed decreases.

Answer:

The box slows down because it collides with the air and causes the air to move.
