Aline and Charlie are arguing as to whether or not it is possible in principle for an elevator to have an acceleration of magnitude greater than. In the course of their discussion they come up with the statements below. Which one is correct?

A.

No, because once   reaches , the elevator is in free fall.

B.
No, because an acceleration greater than is not possible.

C.
Yes, because it can reach an acceleration greater than when the cable breaks.

D.
Yes, because it can reach an acceleration greater than if the motor is strong enough.

E.
No, because it cannot exceed its terminal acceleration.

Snell's Law: A plastic cube is immersed in water having an index of refraction of 1.33. A laser beam in the plastic strikes the interface at an angle of 14.5° with the normal in the plastic. In the water, this beam makes an angle of 21.8° with the normal. What is the speed of light in the plastic cube? (c = 3.0 × 108 m/s)
