the height above the ground of a child on a swing varies from 0.5m at the lowest point to 2.0m at the highest point. what is the maximum speed of the child?
At the local playground, a child on a swing has a speed of 2.12 m/s when the swing is at its lowest point. Part A: To what maximum vertical height does the child rise, assuming he sits still and "coasts"? Ignore air resistance. Part B: How do your results change if the initial speed of the child is halved?
QUESTION 1: A 36.0-kg child swings in a swing supported by two chains, each 2.90 m long. The tension in each chain at the lowest point is 424 N.

A child in a swing is pulled back to a height of h above the lowest point of the swing then released. While the swing moves from height h to its lowest point, how much work is done by the tension force in the ropes of the swing. A.0 B.-2mgh C.2mgh D.-mgh E. mgh
A child on a swing has a speed of 5.5 m/s at the low point of the arc (see the figure below). 5.5 m/s2 How high (in m) will the swing be at the high point?
A 31.0 kg child on a swing is displaced by a maximum angle of 20 degrees to the vertical above her rest position. Assuming no loss of energy and that the swing's rope is 2m long: a) At what point during the swing will she attain her maximum speed? b) What will be her maximum speed through the subsequent swing? c)Assuming this maximum height was the result of one push from her parent, what was the average force exerted by...
