Homework Statement In the system shown all pulleys are light and smooth and all strings are light and inextensible. A block of mass m = 20 kg is attached to the movable pulley. A constant force, F, applied at the free end of the string, makes the point of application of force move down with...

Haha thank you, I got the answer. :)

By adding 10 to 6 and 20 to -8 to get (16i + 12j)?

Yes, I don't know how I'm supposed to take them into account. I thought there's no need to. :S Tell me how to start?
