SPRING PROBLEMS
1. A force of 40.0 N applied to a spring stretches it 80 cm. Find the spring constant, using Hooke’s Law.
2. A force of 12.0 N, when applied to a spring, compresses it a distance of 25 cm. What is the spring constant?
3. When a mass of 2.40 kg is hung on a certain spring, the spring stretches out 60.0 cm. What is the spring constant of the spring?
4. When a 600 g mass is suspended from a spring, the spring stretches 1.2 cm. What is the spring constant of the spring?
5. When a 5.00kg object is placed on a vertical spring, it compresses the spring a distance of 25cm. What is the spring constant of the spring?
6. A spring has a spring constant of 80 N/m. How much force must be exerted in order to compress the spring a distance of 0.40 metres?
7. If a force of 24.0N is exerted against a spring whose spring constant is 160 N/m, what distance will the spring be compressed?
8. A spring has a spring constant of 50.0 N/m. Calculate the amount of work done (Us gained) if the spring is compressed a distance of .40 metres.
9. A spring whose constant is 200 N/m is compressed a distance of 20 cm. How much potential energy did the spring gain?
10. A spring whose constant is 80 N/m is stretched a distance of 30cm. How much work was required to do this?
11. If 100J of work is done in compressing a spring whose constant is 250 N/m, find the distance the spring was compressed.
12. Calculate how much potential energy a spring gains as its compression is changed from a compression of .10m to a compression of 0.50 metres. The spring constant is 200 N/m.
13. A spring has a spring constant of 400 N/m. an object is placed against the spring when it is partly compressed, and is then released so the spring pushes it away. How much kinetic energy will the object gain as the spring goes from a compression of .80m to a compression of only .20 metres? (Hint: Ek gained by mass = U lost by the spring.)
