A 2 kg mass is attached to a spring with k = 44 N/m. To what distance must the spring be stretched in order to store 0.5 J of potential energy? A) 0.568 cm B) 15 cm C) 7.54 cm D) 2.27 cm

1.The work required to stretch a certain spring from an elongation of 4.00 cm to an elongation of 5.00 cm is 30.5 J. (a) Is the work required to increase the elongation of the spring from 5.00cm to 6.00 cm greater than, less than, or equal to 30.5 J?Draw and Explain. (b)Verify your answer to part (a) by calculating the required work.

7. A 60 Kg woman is attached to a bungee cord with an unstretched length of 12m. She jumps off a tower; from a height of 70 m. When she finally stops, the cord has a stretched length of 37m. Assuming the spring constant of the bungee cord is 69.8 N/m, what is the total potential energy relative to the ground when the woman stops falling?

A spring of negligible mass has force constant k = 1600 N/m. How far must the spring be compressed for 3.20 j of potential energy to be stored in it? 7) %3D a) b) The spring is placed vertically with one end on the floor. A 1.0-kg book is the droped from a height of 0.80 m above the top of the spring. Find the maximum distance the spring will be compressed. 1.0 kg h = 0.8 m

As a part of an exercise routine to strengthen their pectoral muscles, a person stretches a spring which has a spring constant k=585N/m

3. When a 4.00-kg object is hung vertically on a certain light spring that obeys Hooke's law, the spring stretches 2.50 cm. If the 4.00-kg object is removed, (a) how far will the spring stretch if a 1.50-kg block is hung on it? (b) How much work must an external agent do to stretch the same spring 4.00 cm from its upstretched position?

An athlete stretches a spring an extra 20.5 cm beyond its initial length. How much energy has he transferred to the spring, if the spring constant is 29.6 N/cm? 622 J 62.2 kJ 62.2 J O 622 kJ
