You measure your weight by stepping on a spring scale inside an elevator. If elevator
accelerates either upward or downward, the spring scale gives a reading different from
your weight. a) Calculate how much a 70 kg person weigh a) if the elevator accelerates
upward with a rate of +1.00 m/s2, b) if the elevator accelerates downward with a rate of
-1.00 m/s2. a) 77 kg b) 63 kg
5)
