Tension $\approx 45$ $approx 45$ and work $\approx - 205.425$ $approx−205.425$

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

Form equation for 5.8

$34 - t = 5.8 a$ $34 - t = 5.8 a$

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

Add up

$34 - 55 = 11.3 a$ $34 - 55 = 11.3a$

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

And tension is (get it by plugging in ); $\approx 45$ $approx45$

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

$W = m a s = - M_{2} t d = - 205.425$ $W = mas = -M_2 t d = −205.425$
