Problem 76GP
At the local playground a child on a swing has a speed of 2.02 m/s when the swing is at its lowest-point. (a) To what maximum vertical height does the child rise, assuming he sits still and “coasts”? Ignore air resistance. (b) How do your results change if the initial speed of the child is halved?
ANSWER:
Step 1 of 5
The objective here is to determine the maximum vertical height the child can reach when he is swinging under the given conditions. Also we have to analyse the variation in the value of the maximum height, if the initial speed of the child becomes half.
