oh and i didn't understand the bit about force because i got something cooky. Gah, I fail at Physics.

so when doing 1/2(30kg)(.01m)^2= .0015So, PE= (.3)(9.81)(.25+.1) PE=1.03 1.03=1/2(.3)(V^2) V=2.62 M.s 2.62^2=0+2(a)(.1m) 6.86=2(a)(.1) a=34.3 m/s^2?

Hey! You did help! Vf=0 haha I am so silly. I'm going to rework it now. (:

Velocity and Acceleration at Maximum Compression (help, test tomorrow??)! Homework Statement A 300g ball compresses a spring 1 cm when just sitting on it (no motion). The ball is dropped onto the spring from 25 cm above the spring at equilibrium. How much will the spring compress as it stops...
