Concept explainers

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

The model airplane in Figure 5.6 is flying at a speed of 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?

Question 3
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.
