A spring of spring constant k=261 N/m is attached to a block of mass 1.38 kg and stretched horizontally to a position 15.0 cm from the springs equilibrium position. The spring and mass are released and oscillate in simple harmonic motion across a frictionless horizontal surface. What is the maximum speed obtained by the mass? m/s

I have a strong spring attached to a wall that has a spring constant of 700 Newtons per meter. Our trusty assistant Ed pulls on the spring and stretches it a distance of 20 centimeters. You then take over from that point and pull to stretch the spring 10 more centimeters so that it is stretched 30 centimeters total from the beginning. Calculate the work done by Ed and the work done by you in this process. At time t...
