The model airplane in Figure 5.6 is flying at a speed 14.6 m/s on a horizontal circle of radius 19.8 m. The mass of the plane is 0.833 kg. The person holding the guideline pulls it in until the radius of the circle becomes 11.3 m. The plane speeds up, and the tension in the guideline becomes four times greater. What is the net work done on the plane? Number i Units Figure 5.6 ΟΝ Scale records tension

Negative in increasing velocity on the downswing; positive in decreasing velocity on the upswing c. Positive in decreasing velocity on the downswing; negative in increasing velocity on the upswing d. Negative in increasing velocity on the downswing; negative in decreasing velocity on the upswing A satellite in circular orbit around the Earth moves constant speed. This orbit is maintained by the force of gravity between the Earth and the satellite, yet no work is done on the satellite. How is this possible? a. No work is done if there is no contact between objects. b. No work is done because there is no gravity in space. c. No work…

samuel has is observing an object. you please determine the work that is done by F = 5i -2j+0k which is a force that is constant in moving samuel's object in a plane . samuel tells you that the object moves due to the force in a straight line in the plane. the straight line connects the points A(1,2) and the point B(3,7). I already know that the correct answer to this question is zero. but the question I have is WHY is it zero. explain why the work is zero in this senario. Not how you get to the answer zero, but why the answer zero can make sense in this scenario. is the forece perpendicualr to the direction? i am confused please help and i will like.
