Find the weight of a 65.0-kg person on the earth (in newtons and pounds).

Solving this problem for calculating the mechanical advantage of the inclined plane. So I will use the formula length of the plane by height of the plane, which is equal to 2.30 m by Euro .75 m, Which is equal to 3.067. No calculating the value of effort pose, which is equal to posts of resistance by mechanical advantage of the inclined planes. So just putting the value here, I can write it as 5500 Newton by 3.067, Which is equal to 1793 .283 Newton as the final answer. So approximate value is one seven 93 newton.

The power off the force is given by musical force. Times were lost. He were forced Isa Mars off elevator plus Mars overlord. This time's the G. There are additional execution times. We Marcel feeling better. We have 4500 k G plus 1800 kg times 9.8 times 3.8 meter per second. This uses the power off the force to be 2 35 kilowatt wars.

We want to calculate force in Newman's recorder to push, eh? 40 kilograms wagon, a 10 degree incline. Well, let's first start off by drawing a free body diagram. So we know we have the force due to gravity here. And then we want to figure out the force required to push it up, which, well, there's a horse going against us in this direction, you know, call it a parallel, and we want to find what force is pushing it down the round. All right, so one thing that might help us is to figure out what this angle right here between these two factors is And you might notice if we slightly scooch it down a little, we would end up with this triangle right here. So this is 10 degrees. This is f parallel. This is F G. And then this here would be a right angle. So then this appear has to be the remaining, so that I would just be 80 degrees. And now, since that's parallel, do this well, we might recall that to get the force of gravity, it would just be the mass times acceleration. Our mass is 40 kilograms. Our acceleration is 9.8 meters per second square and we need to make sure that we use it in meters per second squared. Because if we use it and feet, we won't end up with new tenants or are final answer. And this projections magnitude then because this really is just the projection of are worse on two our ram, This would just be the magnitude Oh, are worse of gravity. Times co side Dana, our co sign Oh, 80 degrees for the angle between them. So we already said that this is 40 kilograms times 9 20 and so clog anal that in that should give us that This is approximately equal to 68.7 new temps. Because remember, a Newton unit is kilograms meters second squared. All right? And so this is how much force we would need to use to keep it in place. So we would just need to do slightly more work than this actually start or to push
