    Need confirmation for spring mass system question

    Homework Statement A mass of 1.20 kg. originally at rest, sits on a frictionless surface. It is attached to one end of an unstretched spring (k = 790 N/m), the other end of which is fixed to a wall. The mass is then pulled with a constant force to stretch the spring. As a result, the system...

    Finding speed of two electrons initially at rest

    Thanks for replying! Oh I don't think I did. So it would be Ee1 = (1/2)mv^2 + (1/2)mv^2.

    Finding speed of two electrons initially at rest

    Homework Statement Two electrons start at rest with a separation of 5.0 x 10^-12 m. Once released, the electrons accelerate away from each other. Calculate the speed of each electron when they are a very large distance apart (Ee = 0). Homework Equations EE = kQq/r Ek = (1/2)mv2 The Attempt at...
