- Homework Statement:
- 1The slider A and the plate B in the figure slide with negligible friction on the vertical guide rod. The plate B is resting on a spring of stiffness k = 30 lb/ft. The slider is released in the position shown and strikes the plate B. The duration of the impact is negligible. Determine the velocity of A immediately before the impact.

- Relevant Equations:
- Conservation of energy: T1 + K1 = T2 + K2

T1 + V1 = T2 + V2

Edit: Accidentally Used two notations for Kinetic Energy in the "Useful equations" section. Changed it to correctly notate Kinetic and Potential. This notation is used in R.C. Hibbeler Dynamics 14th Ed.
