- REMARKS Only simple geometries-rectangles and triangles-can be solved exactly with this method. More complex shapes require calculus or the square-counting technique in the next worked example. QUESTION When stretching springs, does half the displacement require half as much work? (Select all that apply.) U > Yes, because the work is equal to the force times the distance. Yes, because the spring exerts a constant force. Yes, because half the displacement means the force from the spring is half as large. No, because the spring does not exert a constant force. No, because the force of the spring is proportional to x. No, because the force exerted by the spring is proportional to x². X Consider the expression for the work done by an applied force. Under what conditions is the work done equal to simply a value of the force multiplied by the displacement? Do those conditions apply to the present problem - consider why or why not. Consider how the force exerted by the spring depends on its…A child of mass 45 kg stands at the edge of a merry-go-round of mass 120 kg and radius 2.6 m, and both are initially at rest. The child then walks along the edge of the merry-go- round until she reaches a point opposite her starting point as measured on the ground ( point B in the figure below). How far does the child walk as measured relative to the merry - go-round? Start Finish Start Finish В. 3.₁ САA 1.15 kg mass is attached to a 1.86 m string that is anchored to the ceiling. The mass is pulled back to an initial angle of theta = 65.1 degrees and released from rest. (a) How fast is the ball moving at the bottom of its swing — the position indicated in the figure? (b) What is the tension in the string at the bottom of the swing — the position indicated in the figure?
