Aplane leaves atlanta heading northeast (45 degrees) at 100m/s (relative to the girl. the jet stream is blowing at 100m/s to the southwest (45 degrees) (relative to the ground). what is the velocity of the plane relative to the ground?

Consider a system with two masses that are moving away from each other. why will the kinetic energy differ if the frame of reference is a stationary observer or one of the masses?

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

When using the scientist method, which step comes last?
