Can someone please explain this to me? I'm not understanding it whatsoever. This the question:
An object is said to be in free-fall when it is falling with no air resistance acting on the object. The model for the distance an object fall in t seconds is given by the equation d=4.9t2. the distance d is given in meters.
Question:
If the object is falling for 3 seconds, predict the distance the object falls. If a small amount of air resistance is present, predict what this would do to the distance the object falls.

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy. work depends on the square of the change in potential energy. work is equal to the negative of the change in kinetic energy. work is equal to the square of the change in kinetic energy
