Aslingshot has a spring constant of 50 n/m. if you apply a force of 10 n, how far does it stretch?

Idk I have no idea sorry someone else might answer it though.

Kinetic energy = 1/2mv^2. since the mass is constant we can form a ratio of it's kinetic energy at 60 divided by that at 30 to see ke(60)/ke(30) = +(60^2)/30^2). this may be said to 300% increase.
