A 3.2 kg block is hanging stationary from the end of a vertical spring that is attached to the ceiling. The elastic potential energy of this spring/mass sytem is 1.8 J. What is the elastic potential energy of the system when the 3.2 kg block is replaced by a 5.5 kg block? J
An ideal spring hangs from the ceiling. A 1.25 kg mass is hung from the spring, stretching the spring a distance d = 0.0865 m from its original length when it reaches equilibrium. The mass is then lifted up a distance L = 0.0325 m from the equilibrium position and released. What is the kinetic energy K of the mass at the instant it passes back through the equilibrium position? K = d Equilibrium position wwwwww. www
A horizontal spring is compressed by 25.0 cm. A 640.0 g box is then placed against the spring and then released. After travelling 3.15 m from the release point, the speed of the mass is 5.68 m/s. The coefficient of friction is 0.34. What is the spring constant of the spring?
The potential energy of a spring having a fixed end and a mass attached to the other end is given by U=1⁄2 kx^2 where k is the spring constant and x is the displacement from its equilibrium position.

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…
1. In the figure shown, a 300-g block is initially connected to a compressed spring at point A, where x = 60 cm and k = 150 N/m. It was released and started moving along the horizontal surface (uk = 0.15) until it moves up along the inclined surface (uk = 0.25). The box then stops at point D along the incline with 0 = 40°. www.m Fx- A C 0 B A. What is the velocity of the block at point B? B.
