1. The problem statement, all variables and given/known data Relaxed spring is sitting on a horizontal surface. A block is attached at one of its ends is kicked with a horizontal velocity, v1, given to it. The block will move and stretch. Find the distance, x, the spring will stretch. X is in meters. l0=1 m m=1 kg k=1 N/m v1=1 m/s 2. Relevant equations F=-kx T=2∏√(m/k) w=√(k/m) w=v/l0 kx=mrw2 KE=(1/2)mwI 3. The attempt at a solution Plugging in the given and solving for the variables I get w=1 rad/s, T=2∏, l0=1 m. The equation that I get to relate the initial and final lengths is mw2(l0+x)=mwl02 I am having hard time understanding this material. I would really appreciate some help. Thanks.
