I took this course in 1955 and no longer need practice. You are asking basically the same question over and over. I am happy to help but have done enough of them for you.
since it is not extended at the start use y= A cos 2 pi t/T which is A at t = 0 and hits the lowest point, -A at t/T = 1/2
The max extension is 2A down of course, and A=mg/k
A 750g block is attached to a vertical spring whose stiffness constant is 1N/m . The block is released at the position where the spring is unextended.
a) What is the maximum extension of the spring?
How long does it take the block to reach the lowest point?
