X=√0.5^2+0.7^2=0.86 0.5kx^2=0.5*48.2*(0.86)^2=17.34 i found this but i am not sure if the spring is parallel or serial(i take it parallel) This is all i can do.I don't know the rest of the question.

i know the the total mechanical energy is mgh plus 0.5kx^2 but i can't find the answer. answers a)3.127 J b)2.274 m/s

Homework Statement A horizontal slingshot consists of two light, identical springs (with spring constants of 24.1 N/m) and a light cup that holds a 1.21-kg stone. Each spring has an equilibrium length of 50 cm. When the springs are in equilibrium, they line up vertically. Suppose that the...

thanks :)

Homework Statement the speed of surface waves on deep water might depend on the gravitational acceleration has a constant magnitude g,density of water d,and the wavelength of the wave λ.Which one of the following could be how this speed depends on these parameters?(hint:use the dimesional...
