A 0.40 kg mass is attached to a spring with a force constant of 26 N/m and released from rest a distance of 3.2 cm from the equilibrium position of the spring. (a) Give a strategy that allows you to find the speed of the mass when it is halfway to the equilibrium position. (b) Use your strategy to find the speed.© BrainMass Inc. brainmass.com March 4, 2021, 6:23 pm ad1c9bdddf
Solution. We know that mass m=0.40kg, a force constant k=26 N/m. So, we can compute
So, the motion equation is
The solution clearly explains the concepts while solving the problem.
