Question 1045459: URGENT
Hello, I have an urgent problem to be solved... I thank in advance to whoever answers it.
Here it is: "A mass-spring System completes one cycle in 4s. At equilibrium it hangs 50 cm above the floor level. The maximum displacement from equilibrium is 15 cm and at time t=0 it is at the lowest height.
a) Give an equation that represents the position of the mass during its vertical motion as
a function of time.
b) Plot it "
Thanks.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

y = 50-15%2Acos%282pi%2At%2F4%29




Plot y = 50-15%2Acos%282pi%2At%2F4%29 and y = 50 (equilibrium)
