On another day, Kelly took the elevator with her cat Toast. The cat suddenly jumped up vertically with an initial velocity 0 when the elevator started to accelerate. Then Toast fell in the elevator. Assume the initial height of Toast is and the cat was doing free fall (gravity ); the elevator was ascending with a constant acceleration until the cat fell to the ground in the elevator. a. Is the final position of Toast higher or lower than the initial position? Or both are possible? b. When will Toast fall to the ground in the elevator? What's the displacement of Toast from the perspective of someone outside of the elevator?
