1. The problem statement, all variables and given/known
On a very smooth horizontal table, a block of mass m=0.75 kg is attached to an ideal spring with a spring constant k= 242 N/m. The origin of the horizontal coordinate (x=0) is set at the equilibrium position of the block. The block is initially held at a negative position where it keeps the spring compressed. Then the block is released, and moves through position x1=0.105m with a speed v1=1.42 m/s.
a) What was the initial position of the block, x0?
b)What is the maximum speed of oscillation, vmax?
omega = sqrt(k/m
F=-kx
Vmax=A*omega
x=Acos(2pi*f*t)
I thought about using conservation of energy by doing KE+PE=W
W=Fs and KE=1/2mv^2 but I don't think this would give me displacement in terms of a negative/before equilibrium position
