i used the maximum speed equation as the speed would be greatest at x=0 (the relaxed spring length). max speed (mv^2) = k(x^2) 0.017 kg * v^2 = 0.7 N/m * 0.03m^2 from this I got the result of: 0.0371 m/s. I haven't entered it to see, can someone confirm this or show a mistake

A horizontal spring with stiffness 0.7 N/m has a relaxed length of 18 cm (0.18 m). A mass of 17 grams (0.017 kg) is attached and you stretch the spring to a total length of 21 cm (0.21 m). The mass is then released from rest. What is the speed of the mass at the moment when the spring returns to...

ok keep an eye open for it, thank you, I didn't know

I have a similar dilemma that I'm trying to figure out for a friend...it stumped both of us. 2(NaCl) + CuSO4 --> Na2SO4 + CuCl2 it asks for the net ionic equation and what the spectator ions are

that's the problem, everyone says that and i have no idea what is needed equations are needed to figure that out what the conservation of energy is

A comet is in an elliptical orbit around the Sun. Its closest approach to the Sun is a distance of 5e10 m (inside the orbit of Mercury), at which point its speed is 9e4 m/s. Its farthest distance from the Sun is far beyond the orbit of Pluto. What is its speed when it is 6e12 m from the Sun...

i have a question, because its an ellipse how do you determine the radius, or do you mean the distance from the sun to the two points on the ellipse?
