A50 kg person is standing on a bathroom scale in an elevator moving upward.
a.) if the scale reads 56 kg, what is the magnitude of upward acceleration of the elevator (m/s^2)?
b.) now the elevator is traveling up while slowing down. if the magnitude of deceleration is the same as that in part (a), what is reading given by the scale?

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
