I am confused about how to work this problem can anyone take a crack at it? My work is shown in a post below.
Thanks for any and all help!
If the spring is released from rest in the position shown in the picture , the spring contracts pulling the mass to the right. Find the Velocity of the mass when the string and the spring are parallel.
Mass = 1 kg
Spring Constant = K= 800 N/m
Unstretched length of Spring= 1m
Find same answer by using both methods
A) Principle of work and energy
B) Conservation of Energy
