Suppose you muster up the courage to take a walk on the Grand Canyon Skywalk. If you dropped your camera over the railing (hypothetically, of course, because cameras are not allowed), how long would it take the camera to hit the floor of the canyon, which is 1,450 meters below? Use a magnitude of 9.8 m/s2 for gravity and assume no air resistance.
A. 296 seconds
B. 148 seconds
C. 12.1 seconds

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping

With the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 1.90
