Question

if you use the compound pulley, you will need to pull twice the distance but with less force. the force you need is equal to one half the weight of the box plus 25 N. what is the force needed?

Answer 1

(0.25X+25)N

Step-by-step explanation:

-let the weight of the box be X.

-Given that the the force needed is equal to one half the weight of the box plus 25N:

`F_(net)=0.5X+25N\\\\=(0.5X+25)N`

Hence, the total force needed is (0.25X+25)N
