A 43.0-kg child swings in a swing supported by two chains, each 2.98 m long. The tension in each chain at the lowest point is 342 N. (a) Find the child's speed at the lowest point. m/s (b) Find the force exerted by the seat on the child at the lowest point. (Ignore the mass of the seat.) N (upward)

A 26 kg child is on a swing that hangs from 3.0 m long chains as shown in the figure below. What is her maximum speed if she swings out to a 45∘ angle? HINT: Remember that you want to use conservation of energy for this problem. What is special about maximum height? (Remember it's a turnaround point. ) There is a bit of geometry to do. You know how long the chains of the swing are, so how high above the lowest point is the seat of the swing when it is at its maximum height? Make sure to draw a picture and figure out the different lengths. What is the child's maximum speed? m/s

An adult exerts a horizontal force on a swing that is suspended by a rope of length L, holding it at an angle θ with the vertical. The child in the swing has a weight W and dimensions that are negligible compared to L. The weights of the rope and of the seat are negligible. In terms of W and θ, determine a. the tension in the rope; b. the horizontal force exerted by the adult. The adult releases the swing from rest. In terms of W and θ determine c. the tension in the rope just after the release (the swing is instantaneously at rest); d. the tension in the rope as the swing passes through its lowest point.

See Conceptual Example 6 to review the concepts involved in this problem. A 13.6-kg monkey is hanging by one arm from a branch and swinging on a vertical circle. As an approximation, assume a radial distance of 79.6 cm is between the branch and the point where the monkey's mass is located. As the monkey swings through the lowest point on the circle, it has a speed of 1.20 m/s. Find (a) the magnitude of the centripetal force acting on the monkey and (b) the magnitude of the tension in the monkey's arm. (a) Number Units (b) Number Units
