heavy block is suspended from a vertical spring. The elastic potential energy stored in the spring is 0.80 J. What is the stretch of the spring if the spring constant is 100.0 N/m?  Question 11 options:   2 .0 cm   4.0 cm   8.0 cm   10.0 cm   13.0 cm

A 1.81-kg box rests atop a massless vertical spring with k = 3820 N/m that has been compressed by 11.4 cm from its equilibrium position. The box is released and leaves the spring when it reaches its equilibrium position. What is the maximum height the box reaches above its original position? In m

A physical therapist is directing a rehabilitation session with a patient recovering from knee surgery. The physical therapist prescribes some knee extension exercises that involve an elastic band. The stiffness of the band that the patient uses is 1500 N/m.  What is the force exerted by the band if it was stretched by 6.5 centimeters? What is the elastic potential energy stored in the band when it was stretched

Tom has built a large slingshot, but it is not working quite right. He thinks he can model the slingshot like an ideal spring with a spring constant of 35.0 N/m. When he pulls the slingshot back 0.375 m from a nonstretched position, it just does not launch its payload as far as he wants. His physics professor "helps" by telling him to aim for an elastic potential energy of 17.0 J. Tom decides he just needs elastic bands with a higher spring constant. By what factor does Tom need to increase the spring constant to hit his potential energy goal? factor of spring constant increase: During a follow-up conversation, Tom's physics professor suggests that he should leave the slingshot alone and try pulling the slingshot back further without changing the spring constant. How many times further than before must Tom pull the slingshot back to hit the potential energy goal with the original spring constant? factor of pullback distance increase: In which of the two scenarios does Tom have to pull…

A spring of spring constant k = 12.3 N/m is compressed from it's equilibrium position by 28.1 cm. How much energy is stored in the elastic potential energy of the spring?

A spring with a spring constant of 51.1 N/m is hung from the ceiling. A block is then attached to the free end of the spring. When released from rest, the block drops 0.160 m before momentarily coming to rest, after which it moves back upward. What is the mass of the block?

How far does it drop before coming to rest? (Assume the spring is unlimited in how far it can stretch.)

A 900 kg safe is 1.5 m above a heavy-duty spring when the rope holding the safe breaks. The safe hits the spring and compresses it 40 cm. What is the spring constant of the spring? Express your answer to two significant figures and include the appropriate units.
