If you were to drop a rock from a tall building, assuming that it had not yet hit the ground, and neglecting air resistance, after it has fallen 22 m: how much time has passed (in s)? what is the speed at this distance (in m/s)?

What is the stall speed at sea level of an airplane that weights 10000 lbs., has a wing area of 300ft^2, and a maximum lift coefficient of 1.4? what is the stall speed if flaps that double cl,max are applied?

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

The law of reflection states that the angle of reflection is equal to the angle of
