Question #1ec1b

Answer 1

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

Explanation:

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`
