The spring of a spring balance is 7 cm long when there is no weight on...
7. A force of 40 N is required to hold a spring that has been stretched from its natural length of 10 cm to a length of 16 cm. How much work is done in stretching the spring from 13 cm to 17 cm?
(1 point) 5 Joules of work are done when stretching a spring from it's natural length to 11 cm beyond it's natural length. What is the force (in Newtons) needed to stretch the spring 11 cm?
A spring has a natural length of 22 cm. If a 28-N force is required to keep it stretched to a length of 40 cm, how much work w is required to stretch it from 22 cm to 31 cm2 (Round your answer to two decimal places.) W =
An ideal spring of negligible mass is 11.00 cm long when nothing is attached to it When you hang a 3.05-kg weight from it, you measure its length to be 12 50 cm. If you wanted to store 10.0 J of potential energy in this spring, what would be its total length? Assume that it continues to obey Hooke's law. Express your answer numerically. If there is more than one answer, enter each answer, separated by a comma. Incorrect;; 3...
A 12 cm long spring is attached to the ceiling. When a 2.6 kg mass is hung from it, the spring stretches to a length of 17 cm.(a) What is the spring constant k?
To stretch an ideal spring 9.00 cm from its unstretched length, 19.0 J of work must be done. Part A What is the force constant of this spring? Express your answer with the appropriate units. Part B What magnitude force is needed to stretch the spring 9.00 cm from its unstretched length? Express your answer with the appropriate units. Part C How much work must be done to compress this spring 4.00 cm from its unstretched length? Express your answer...
A 10-cm-long spring is attached to theceiling. When a2.0 kg mass is hung from it,the spring stretches to a length of 15 cm. a.What is the spring constant k? b.How long is the spring when a 3.0kg mass is suspended from it?
C) A 9.0-cm-long spring is attached to the ceiling. When a 1.5 kg mass is hung from it, the spring stretches to a length of 18 cm . - What is the spring constant k? - How long is the spring when a 3.0 kg mass is suspended from it?
A 12-cm-long spring is attached to the ceiling. When a 1.6 kg mass is hung from it, the spring stretches to a length of 18 cm . Part A What is the spring constant k? Part B How long is the spring when a 3.0 kg mass is suspended from it?
An elastic cord is 70 cm long when a weight of 80 N hangs from it but is 84 cm long when a weight of 200 N hangs from it. What is the "spring" constant k of this elastic cord? Express your answer to two significant figures and include the appropriate units.
