okay. We'd like to calculate the work done to you lift £100.4 feet vertically. So obviously we're, uh, work is equal to force times direction on, uh, cause of our angle. We're lifting it absolutely vertically, so it's just cause of zero. So it's a one to have to worry about that. So what? So all we have to worry about his fourth on distance while our distance is great. Before we told it's four feet on, we've given ah, a mass off £100. So to get his force will have to times that by gravity. So just simply 100 times by 9.8, which will give us 980 my answer is calculate work done. We said we just have to do 980 times by four, which should give us 3920
