If you accidentally drop a portable computer with an accelerometer installed, the device detects it and puts the hard drive into safe mode. After installing a program on the computer that reads the accelerometer and calculates the apparent weight of the computer, the computer was carried on a long flight. The computer weighs $5$ pounds, and the program continued to report that way during the flight. Then, for $12$ seconds, when the plane suddenly encounters turbulence and fluctuates, the apparent weight of the computer reported by the program is depicted in Figure $4\mathrm{.}27$
