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…
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?
4. A spring with an equilibrium length of 50.0 cm is holding a 4.00kg mass. The mass causes the spring to stretch to a length of 1.00 meter. What is the potential energy given to the spring?

Someone Suppose you are working on designing a t-shirt launch cannon that works via a spring mechanism and still want to launch that t-shirt to Smeone. If you plan to launch at 45 degrees, need a speed of 30 m/s and the cannon is 0.2 meters long... A. What is the final kinetic energy of the 2.0 kg t-shirt upon leaving the cannon? E. What must the spring constant be to reach this final speed? C. If instead you launched the t-shirt straight up, what maximum height would it reach?
