A person uses a lever to lift a load. The person pushes downward with a force of 17 N a vertical distance of 1.8 m.

Under ideal condidtions (no friction, bending, etc.), how high up can a load weighing 610 N be lifted?

h(lift)=_____cm

h*610=1.8*17

work in= work out

I'm still confused.
I get the work in=work out but i don't understand what you're doing. I tried doing it your way, but it still gave me the wrong answer, even when i tried converting it to cm.

workin=17*1.8 joules
workout=610*H

set them equal.

n= 17*1.8/610= appx 5cm
