1981B2. A massless spring is between a 1 kilogram mass and a 3 kilogram mass as shown above, but is not attached to either mass. Both masses are on a horizontal frictionless table. In an experiment, the 1 kilogram mass is held in place and the spring is compressed by pushing on the 3...

So do i just set the kinetic energy of the masses equal to the potential energy of the spring like so: (1/2)mv^2 = (1/2)(k)(x)^2 ==> .5(1.5)(.4)^2 = .5(100)(x)^2 ==> .12J = 50x^2 so .0024 = x^2 ==> and Squareroot(.0024) = .0489m = x Then I plugged it in F = kx and got 4.89N which is the force...

I get that but don't I have to do something with the spring?

Homework Statement A .2kg mass traveling on a frictionless horizontal surface at a speed of 3 m/s. It hits a 1.3 kg mass at rest that is connected to a massless spring with a a spring constant of 100 Newtons per meter. The other end of the spring is fixed. Calculate the linear momentum and...
