(a) IF each elastic band stretches 0.250 m while supporting a 7.70 kg child, what is the force constant for each elastic band? 100.7 N/m (b) What is the time for one complete bounce of this child? X What variables affect the period of a spring? s c) What is the child's maximum velocity if the amplitude of her bounce is 0.250 m? At what point does the child have a maximum speed? A minimum speed? Can you relate the two points with energy conservation? What types of energy are relevant? m/s Additional Materials Reading
