Tension #approx 45# and work# approx−205.425 #

I am not too sure about this but I recommend you ask your intructer the exact way

Form equation for 5.8

#34 - t = 5.8 a#

Form equation for 5.5
#t - 55 = 5.5 a #

Add up

#34 - 55 = 11.3a#

Solving # -21 = 11.3 a# we get# a = -1.86# rounded

And tension is (get it by plugging in ); #approx45#

Now notice that acceleration is negative now this contradiction tells us that the body move the other way

#W = mas = -M_2 t d = −205.425 #
